DriversBest Drivers 2026 | 6 Drivers Analyzed for Distance, Ball Speed and Dispersion
Updated: Oct 5, 2026Contains affiliate links
Six drivers from six brands, compared on official numbers
The 2026 drivers are all out. This article ranks six: the Callaway QUANTUM Triple Diamond (◆◆◆), Titleist GTS2, Srixon ZXi RKT, TaylorMade Qi4D, PING G440 K and Cobra OPTM. They look alike, but through a gear nerd's eyes, the shape and where the CG sits change their character quite a lot. The order is what I, a golfer who averages 72, would choose for my own bag. First, the criteria.
How this ranking was decided
The inputs are manufacturers' official specs plus sourced third-party measurements and test articles. None of the numbers are my own measurements. I judged 5 categories separately and checked them against the scores in my review roundup.
The final order is what I, a golfer who averages 72, would choose for my own bag. The 5 categories are yardsticks that apply to anyone, so the number of ◎ marks in the table does not match the ranking. I give the reason rank by rank.
- ① Distance: launch angle and spin, and third-party measured gains over the previous model. Numbers taken under different conditions (head speed, robot vs human) aren't compared side by side
- ② Ball speed: ball speed on center and on off-center hits. I check whether the manufacturer's claims match the testers' verdicts
- ③ Dispersion: measured moment of inertia (how well the head resists twisting on off-center hits), draw/fade bias, and forgiveness
- ④ Adjustability: the loft and lie range of the hosel sleeve, and whether there are movable weights
- ⑤ Price: MSRP and the lowest price on price-comparison sites (with the date checked)
Categories with no published numbers are marked "not published" and given no rating.

How to choose a driver: 5 points to avoid mistakes
Point 1: Choosing by dispersion rather than distance does more for your score
Gaining 10 yards doesn't help if you're 30 yards offline; your stroke count goes up. A club with less left-right spread lowers your average score.
Point 2: The difference of one model year is often buried in the spread
When the same person hits 10 balls, distance varies by 20+ yards. A catalog's "few yards" can't be spotted inside that. Decide on upgrading by the average and spread of 10 balls.
Point 3: Don't choose loft out of pride
The slower your head speed, the more too little loft keeps the ball from getting up and costs you distance. Decide by checking launch angle and spin in a fitting or demo.
Point 4: The shaft can matter more than the head
Even with the same head, shaft weight and flex change your timing. Revisiting the shaft before changing the head can also be cheaper. If the problem is lack of distance or curving shots, I suspect the shaft before the head.
Point 5: Last year's model is a sensible choice
Right after a new model is announced, used prices for last year's model drop. If the performance gap is within the spread, putting the money saved into practice does more. I still play a Qi10 Max myself.
Analysis by category | Best overall: QUANTUM ◆◆◆
I compared the six across the 5 categories described above, listed in ranking order. ◎ means there is evidence it stands out among the six, ○ means it is about standard, and △ means a measurement or review points to a weakness.
| Model | Distance | Ball speed | Dispersion | Adjustability | Price | Review score |
|---|---|---|---|---|---|---|
| Callaway QUANTUM ◆◆◆ | ○ Longest in Sportsnavi's 4-model comparison. No measurement under the same conditions as other brands | ○ The 3-layer TRI-FORCE face is shared across the series. I found no ball speed measurement for the ◆◆◆ alone | △ A 450cc head for better players. Little help off the center. Measured MOI not confirmed | ○ Loft −1 to +2°, two lie settings. The rear weight sets neutral or fade | △ From ¥118,800. ¥11,000 more than the previous model. Select stores in Japan only | 4.0 |
| Titleist GTS2 | △ Center-strike numbers "about the same" as the previous GT2 (Golf Monthly) | ○ Ball speed and spin stay stable when strike location shifts (GDO, overseas magazines) | ○ Measured 4,797, or 5,056 with the weights swapped | ◎ SureFit plus swappable 11g front and 5g rear weights; 3–15g weights sold separately | △ MSRP ¥115,500, lowest about ¥101,600 | 3.9 |
| Srixon ZXi RKT | ○ Carry +7.7 yards vs. the previous model in a third-party measurement (Masa) | ◎ Ball speed of 68.0 m/s (about 152 mph) in the same measurement, +2.4 m/s (about 5 mph) vs. the previous model. The LS holds its speed off the center (ALBA) | △ Left-right dispersion of ±9.5 yards (Masa). MOI not published | ◎ 12-position sleeve plus swappable weights (10g / 4g) | ◎ MSRP of ¥89,100, the lowest among the major brands' 2026 460cc releases | 3.8 |
| TaylorMade Qi4D | ○ Split: +4.6 y vs previous model (Masa) and "same as previous" (Yoshikazu Matsuo) | ○ COR same as previous model (Matsuo) | ○ Measured MOI 5,095; MAX is 5,702 | ◎ Movable weights on all 4 models | ◎ MSRP ¥107,800, lowest ¥65,534 (Sep 14) | 3.8 |
| PING G440 K | ○ +4.3 y carry vs previous model in PING's comparison test. Spin on the high side (test average 3,264 rpm) | △ "A step behind" rivals' models from the same period (Takuya Taniguchi, GDO) | ◎ Measured 5,859, the highest of 21 models measured | ○ Loft ±1–1.5°, 2 lie settings, 3 rear weight positions | △ MSRP ¥118,800. ¥11,000 more than the G440 MAX | 3.4 |
| Cobra OPTM | Not published | Not published | Not published | ◎ Loft and lie ±2°, 33 settings (official) | ○ Official store ¥93,400 (tax status not stated). Street price not checked | Not scored |
My top overall pick is the Callaway QUANTUM ◆◆◆ (Triple Diamond).
Let me say this up front: the ◆◆◆ has not a single ◎ in the table above. That is because the 5 categories are yardsticks that apply to anyone. The ranking is what I, a golfer who averages 72, would choose for my own bag.
The rules cap how springy a driver face can be (a COR of 0.830), so one model year newer leaves little room for a big jump in ball speed. So where does the difference come from? As I see it, from whether shape and weight placement let you produce the ball flight you want.
The ◆◆◆ is a compact 450cc pear shape. The rear weight sets neutral or fade, so it moves only in the direction that reins in the left miss. Both the crown and the sole are carbon, and the saved weight goes into placement. The face is the same 3-layer TRI-FORCE as the MAX. The ball speed technology stays common to the series, while shape and weight go all-in on working the ball. That commitment is why it is No. 1.
The weak points are just as clear. It gives little help off the center. It starts at ¥118,800 and is sold only at Callaway Selected Stores in Japan. It is for better players, not for everyone. If your strike wanders, or you struggle to square the face and miss right, you don't need it. The QUANTUM MAX with the same face, or the G440 K, rated ◎ for dispersion, comes first.
No. 2 is the Titleist GTS2. The GTS2 and GTS3 are really good. I think they are future classics. The GTS2 has a measured MOI of 4,797, or 5,056 with the front and rear weights swapped (Muneyuki Matsuyoshi, GDO). GDO and overseas reviews agree that ball speed and spin stay consistent when the strike wanders. Two things keep it from No. 1. Its numbers on center strikes are about the same as the previous GT2 (Golf Monthly), so the distance gain is small. And the GTS2 is the high-launch, mid-spin model whose job is forgiveness. For range of shot-shaping, the compact ◆◆◆ wins. I am still torn between the GTS2 and the GTS3 myself.
No. 3 is the Srixon ZXi RKT. The Srixon is hard to pass up too. Its ¥89,100 MSRP is the lowest among the major brands' 2026 460cc releases. Yet it has a forged titanium face and a 12-position sleeve. In a third-party measurement, ball speed was up 2.4 m/s (about 5 mph) over the previous model (“Masa's Golf Notebook” blog). It misses No. 2 because MOI is not published, so its forgiveness can't be checked by the numbers. Left-right dispersion in the same measurement was ±9.5 yards; this is not a club you buy for help off the center. That part is so-so.
No. 4 is the TaylorMade Qi4D. Its balance of adjustability and price is still the best. All four models get movable weights, and it is the first time they reach the forgiveness-minded MAX and MAX LITE in TaylorMade's MAX line (official release). Against an MSRP of ¥107,800, the lowest price on Sep 14 was ¥65,534. I still put it fourth because one measurement shows both distance and face rebound level with the previous model (Yoshikazu Matsuo). Its overall review score is 3.8, the same as the ZXi RKT, so it is a close call. Draw bias is modest, so if you fight a slice, the G440 K comes first. And if you're happy with the previous Qi35 and only want more distance, I don't think you need to buy it.
The winner in each category is as follows.
- Distance: I didn't separate the six, because the measurement conditions don't line up. Widen it to 8 models and it's the PRGR RS (distance design 4.5)
- Ball speed: Srixon ZXi RKT. 2.4 m/s (about 5 mph) faster than the previous model in a third-party measurement. For holding speed off the center, it's the QUANTUM MAX, where several tests agree
- Straightness: PING G440 K. Its measured MOI was the highest of 21 models measured
- Adjustability: for loft and lie range, the Cobra OPTM (±2°, 33 settings). If you also want to move weight, the Qi4D
- Price: on MSRP, the ZXi RKT (¥89,100). On street price, the QUANTUM MAX, at about 43% off MSRP (Sep 14)
The QUANTUM and GTS are ranked by model, not by series. I cover the QUANTUM MAX and the GTS3 and GTS4 in my QUANTUM review and GTS review.
Bottom line first: choose by 3 types
| If you | What suits you | Candidates |
|---|---|---|
| Want to work the ball with head shape | Compact, with adjustment that reins in the left miss | Callaway QUANTUM ◆◆◆, Titleist GTS3 |
| Want consistent distance when the strike wanders, and less curve | Strong on off-center hits | Titleist GTS2, PING G440 K, Callaway QUANTUM MAX |
| Want to choose on price and range of adjustment | Low MSRP or street price, and tunable after you buy | Srixon ZXi RKT, TaylorMade Qi4D, Cobra OPTM |

No. 1 Callaway QUANTUM ◆◆◆ (Triple Diamond)
Rakuten Ichiba / Ad
Callaway QUANTUM ◆◆◆ (Triple Diamond)
From ¥118,800 (varies by shaft; sold only at Callaway Selected Stores in Japan / Callaway official press release 2026-01-19)
A compact 450cc pear shape. This is the model for better players who want to work the ball with head shape. The ◆◆◆ is sold only at select stores in Japan, so the photo and the button below are for the QUANTUM MAX from the same series.
See on Rakuten Ichiba (QUANTUM MAX, Japan-market model)See on Yahoo! Shopping JapanWhy No. 1? Because it is the most single-minded design of the six. A compact 450cc pear shape, with a weight that moves only in the direction that reins in the left miss. The 3-layer face that produces ball speed is the same as the MAX, while shape and weight placement lean toward working the ball. If I, a golfer who averages 72, were choosing one driver for my own bag on construction and numbers, this is it. But it is for better players, not for everyone. It gives little help off the center. I rank it No. 1 knowing that.
Key points
- 450cc, pear shape. Lofts of 9.0° / 10.5° (8.0° made to order), 57° lie, 45.5 inches
- Swap the rear weights (about 9g and about 1g) to choose neutral or fade. The MAX offers draw or neutral, so it moves the opposite way
- Both the crown and the sole are carbon (360° Carbon Chassis). Callaway says this frees up weight distribution to push distance and workability as far as possible
- The face has three layers of titanium, polymer and carbon (TRI-FORCE). The titanium layer is 14% thinner than on the previous ELYTE. This is shared across the series, not unique to the ◆◆◆
It suits players who want to work the ball with a compact head and players who want to rein in the left miss. Test articles suggest a head speed of 45 m/s (about 101 mph) or more. It does not suit players who put help off the center first, or players who struggle to square the face and miss right. I also don't recommend it if you can't get to a select store. In that case, start with the 460cc QUANTUM MAX, which has the same face.
Pros
- A compact pear shape and a weight set to rein in the left miss. A design that goes all-in on working the ball
- The 3-layer face is the same as the MAX. Nothing is cut from the ball speed technology
- Longest in the series in Sportsnavi's 4-model comparison
Cons
- Little help off the center. If your strike wanders, it is honestly tough
- Sold only at Callaway Selected Stores in Japan, so you can't buy it just anywhere
- From ¥118,800. Up ¥11,000 from the previous model

No. 2 Titleist GTS2 Driver
Rakuten Ichiba / Ad
Titleist GTS2 Driver
¥115,500 (TENSEI) / ¥137,500 (TOUR AD), both incl. tax, official, checked Sep 12, 2026
Of the 3 GTS models, this is the one whose job is forgiveness. 460cc, with lofts of 8 / 9 / 10 / 11°. Released on Jun 11, 2026.
See on Rakuten Ichiba (¥115,500, as of Sep 12, 2026)See on Yahoo! Shopping JapanWhy No. 2? The GTS2 and GTS3 are really good. They are future classics. The GTS2 has a measured MOI of 4,797, and ball speed and spin stay consistent when the strike wanders. It misses No. 1 because its numbers on center strikes are about the same as the previous GT2, so the distance gain is small, and because it gives way to the compact ◆◆◆ on range of shot-shaping. I put it above No. 3 because its forgiveness is backed by a measured number. For the ZXi RKT, that figure is not published. I am still torn between the GTS2 and the GTS3 myself, and for the ranking I went with the GTS2, the one that handles a wandering strike better.
Key points
- The GTS2, GTS3 and GTS4 are all 460cc and the same price. You don't choose among them by size. The higher the number, the easier it is to keep spin and launch down
- The GTS2's weights are 11g front and 5g rear. Swap them and the measured MOI goes from 4,797 to 5,056 (Muneyuki Matsuyoshi, GDO)
- The TENSEI and TOUR AD shaft options differ in price by ¥22,000.
It suits players who want consistent distance even when the strike wanders, players who want a higher flight, and players who need 11° of loft. It does not suit strong slicers. Some reviews say even the GTS2 lacks draw bias. If you're happy with the previous GT2, you don't need it either. If you want the left miss gone, or prefer a compact head at address, take the GTS3 (GDO's test suggests a head speed of 40 m/s (about 89 mph) or more).
Pros
- Ball speed and spin stay consistent when the strike wanders. GDO's test and overseas reviews agree
- SureFit hosel plus weights that swap front to back. Weights sold separately run 3–15g
- Release date, price, loft and head volume were confirmed in the official news release.
Cons
- Numbers on center strikes are about the same as the previous GT2 (Golf Monthly)
- Some note the sound gets hard and rings metallic off the center (Golf Monthly)
- MSRP of ¥115,500 is ¥7,700 more than the previous model. TOUR AD shafts add another ¥22,000
| Head volume | 460cc (GTS2, GTS3 and GTS4) |
|---|---|
| Loft options | GTS2 and GTS3 = 8 / 9 / 10 / 11°, GTS4 = 8 / 9 / 10° |
| Shafts | TENSEI 1K White 65 RIP / Blue 55 RIP / Red 55 and 45 RIP, TOUR AD DI 6, TOUR AD FI 6 |
| Weights | GTS2 = 11g front, 5g back; GTS3/GTS4 = track + flat, 8g front, 5g back |

No. 3 Srixon ZXi RKT Driver
Rakuten Ichiba / Ad
Srixon ZXi RKT Driver
¥89,100 (MSRP, same for all 4 models / Dunlop official)
4 models: standard, MAX, LS and TR. The face technology, 45.75 inches and ¥89,100 are shared by all 4.
See on Rakuten Ichiba (ZXi RKT)Why No. 3? The Srixon is hard to pass up too. Its ¥89,100 MSRP is the lowest among the major brands' 2026 460cc releases, yet it has a forged titanium face and a 12-position sleeve. The price was cut; what's inside was not. It misses No. 2 because MOI is not published, so its forgiveness can't be checked by the numbers. Its overall review score is 3.8, the same as the No. 4 Qi4D, so it is a close call. I put it higher because one measurement shows ball speed up 2.4 m/s (about 5 mph) over the previous model.
Key points
- The angle and loft of the upper face change from spot to spot. Srixon says this reins in excessive hook spin on strikes high on the toe
- A 12-position sleeve plus swappable weights (10g and 4g). Stock is 4g toe and 10g heel; swap them to adjust left-right curve
- The four models differ in head size and weight placement. The MAX has 10g in the rear and curves the least; the LS and TR are lower-spin with 10g front and 4g rear. Only the TR is a compact 450cc
It suits players whose strikes cluster above the center or toward the toe, and players who want a major brand's new model with an MSRP under ¥90,000. It does not suit players who put help off the center first. For them the G440 K comes first. Testers are split on the sound, so if sound matters to you, I don't recommend buying without a trial either.
Pros
- MSRP of ¥89,100, the lowest among the major brands' 2026 releases (460cc models sold in stores)
- Forged titanium face and a carbon crown. All four models are labeled made in Japan
- A third-party measurement showed ball speed up 2.4 m/s (about 5 mph) over the previous model (Masa's Golf Notes)
Cons
- MOI figures aren't published, so you can't compare its stability with other brands by the numbers
- Forgiveness does not stand out. Left-right dispersion in the same measurement was ±9.5 yards
- Testers disagree on the sound and on how much draw bias it has
| Model | ZXi RKT (standard) / MAX / LS / TR |
|---|---|
| Head volume | 460cc (TR is 450cc) |
| Loft options | 9 / 10.5° |
| Length | 45.75 in |
| Adjustability | 12-position QTS sleeve + swappable weights |
| Weights | Standard: 4g toe, 10g heel. MAX: 10g rear. LS and TR: 10g front, 4g rear |
No. 4 TaylorMade Qi4D Driver
Rakuten Ichiba / Ad
TaylorMade Qi4D Driver
¥107,800 (incl. tax, Japan-market model on Rakuten, REAX graphite shaft, as of Sep 12, 2026). Another outlet lists ¥124,300, likely due to a different shaft spec
The brand's main 2026 model. There are 4 models (Qi4D / LS / MAX / MAX LITE), so you can lean toward forgiveness or workability.
See on Rakuten Ichiba (¥107,800, as of Sep 12, 2026)See on Yahoo! Shopping JapanWhy No. 4? Its balance of adjustability and price is still the best of the six. All four models get movable weights, and against an MSRP of ¥107,800 the lowest price had fallen to ¥65,534 (Sep 14). I still put it fourth because one measurement shows both distance and face rebound level with the previous model (Yoshikazu Matsuo), and the measured MOI is down from the previous model's 5,355 to 5,095. It ties the No. 3 ZXi RKT at 3.8 overall, a close call, and the two swap places if price comes first for you. It ranks above No. 5 because of the gap in overall score, 3.8 against 3.4.
Key points
- With 4 models, first pin down whether it's the MAX or the LS. As a gear nerd, I find reviews that just say "Qi4D" hard to act on, because you can't tell which model they mean
- I couldn't confirm the loft options, head volume or release date on the official page. If you want to compare numbers, check the official page or in store before buying
- Prices are split between ¥107,800 and ¥124,300 depending on the outlet. It's likely a shaft-spec difference, so don't compare on price alone
Good for golfers who want more ball speed without losing forgiveness, and those looking to upgrade from the Qi10 series. Not for those already happy with a Qi10 or Qi35. The difference of one model year is often buried in the 10-ball spread, and I don't think it's much reason to give up a previous model that suits you.
Pros
- The Japan-market model (official distribution) on Rakuten (REAX graphite shaft) is ¥107,800, about ¥16,000 less than the ¥124,300 listed by another outlet
- 4 models (Qi4D / LS / MAX / MAX LITE), so you can lean toward forgiveness or workability
Cons
- I couldn't confirm the loft options, head volume or release date on the manufacturer's official page
- Prices are split between ¥107,800 and ¥124,300 depending on the outlet. Likely a shaft-spec difference

No. 5 PING G440 K Driver
Rakuten Ichiba / Ad
PING G440 K Driver
¥118,800 (incl. tax, official, checked Sep 12, 2026)
The draw-bias model in PING's G440 series, for players who want fewer misses to the right. Released Feb 5, 2026.
See on Rakuten Ichiba (¥118,800, as of Sep 12, 2026)See on Yahoo! Shopping JapanWhy No. 5? It curves the least of the six. Its measured MOI of 5,859 was the highest of the 21 models measured (GDO). I put it fifth because reviewers rate its ball speed a step behind other brands' models from the same period (Takuya Taniguchi, GDO), and because of the high ¥118,800 MSRP. Its overall review score is 3.4. If you fight a slice, this is your No. 1. It ranks above No. 6 because there is enough material to check it by the numbers.
Key points
- Loft adjusts ±1° and ±1.5°, and lie can be set to standard or flat. Being able to go flat when the draw bias feels too strong is, in my view, an important safety valve on a draw-biased club.
- Besides the stock Japan-only ALTA J CB BLUE shaft, you can also choose TOUR 2.0 or SPEEDER NX GREY.
- There's a G440 K HL variant. Head volume 460cc, total weight about 301g.
Suits players who want to stop slicing and tighten their left-right dispersion. Not ideal for players who like to curve the ball on purpose: the draw bias can make it hard to hold the ball out to the right.
Pros
- Price, loft, head volume, shaft and adjustment range could all be confirmed with the manufacturer
- Adjustable loft ±1° / ±1.5° and standard or flat lie.
Cons
- ¥118,800. That's ¥11,000 more than the G440 MAX / SFT / LST (¥107,800 each).
- It's built to help square the face, so it doesn't suit players who want to hit a fade on purpose.
| Head volume | 460cc |
|---|---|
| Loft options | 9 / 10.5 / 12° |
| Total weight / swing weight | About 301g, D3 (lie 59.5°) |
| Stock shaft | ALTA J CB BLUE (R/SR/S, Japan only), other options available |
| Adjustability | Loft ±1° / ±1.5°, lie standard or flat |
No. 6 Cobra OPTM Driver (OPTM X and others)
Rakuten Ichiba / Ad
Cobra OPTM Driver (OPTM X and others)
OPTM X driver ¥93,400 (official online store listing, tax status not stated; checked Sep 12, 2026)
Loft and lie adjust in 33 combinations. For players who want to keep dialing it in after buying.
See on Rakuten Ichiba (OPTM X)See on Yahoo! Shopping JapanWhy No. 6? Its adjustment range, loft and lie ±2° through 33 settings, is the widest of the six. But no numbers are published for distance, ball speed or dispersion, and my review has not scored it yet. I can't rank high what I can't check by the numbers, so it is sixth.
Key points
- FutureFit33 adjusts loft and lie in 33 settings within ±2°.
- Cobra says SMARTPAD keeps the face square at every setting.
- OPTM is the series name. X / LS / MAX-K / MAX-D each have a different character.
Suits players who want to tinker with the adjustable hosel and dial it in themselves. Less suited to players who value demo opportunities in Japan: it may be stocked by fewer shops than the other three brands.
Pros
- Loft and lie can be fine-tuned within ±2°, so you can keep fitting it to yourself after purchase.

One thing before you buy
When a new model “goes X yards farther,” that X is usually not something anyone can measure.
Hit 10 balls with the same club and your distance varies by 20+ yards. The gap between model years (a few yards) gets lost in that spread. If you hit one or two balls in a demo and it “felt long,” that may just be a lucky swing.
When you test in a shop, hit 10 balls with the same club and look at the average and the spread. Enter them into our shot dispersion notebook (free, no sign-up) and it calculates them on the spot.
Consider last year's model
A new model launch is also your cue that last year's model is about to get cheaper. If the performance gap is lost in your dispersion, I think many players are fine with the older model. I still use a Qi10 Max myself.
Why This Order
This is the order I, a golfer who averages 72, would choose for my own bag. It does not match the number of ◎ marks in the category table above. This is not a sales ranking.
| Rank | Model | Why I ranked it here |
|---|---|---|
| 1st | Callaway QUANTUM ◆◆◆ | A compact 450cc pear shape, with a rear weight that moves only in the direction that reins in the left miss. The face is the same 3-layer design as the MAX. I ranked it No. 1 for a design whose shape and weight placement go all-in on working the ball. It gives little help off the center and is sold only at select stores in Japan. It is not for everyone. |
| 2nd | Titleist GTS2 | Measured MOI of 4,797, or 5,056 with the weights swapped. Ball speed and spin stay consistent when the strike wanders. It is a future classic. It misses No. 1 because its numbers on center strikes are about the same as the previous GT2, and on range of shot-shaping. I put it above No. 3 because its forgiveness is backed by a measured number. |
| 3rd | Srixon ZXi RKT | Its ¥89,100 MSRP is the lowest among the major brands' 2026 460cc releases. Yet it has a forged titanium face and a 12-position sleeve. It misses No. 2 because MOI is not published, so its forgiveness can't be checked by the numbers. It ties No. 4 at 3.8 overall, a close call; the measurement showing ball speed up 2.4 m/s (about 5 mph) over the previous model put it ahead. |
| 4th | TaylorMade Qi4D | Its balance of adjustability and price is still the best of the six. Movable weights on all four models, and an MSRP of ¥107,800 against a lowest price of ¥65,534. It is fourth because one measurement shows distance and face rebound level with the previous model. If price comes first for you, it swaps places with No. 3. |
| 5th | PING G440 K | Dispersion is ◎. Its measured MOI of 5,859 is the highest of the 21 models measured. It is fifth because ball speed and price are both △ and its overall score is 3.4. If you fight a slice, this is your No. 1. |
| 6th | Cobra OPTM | Adjustability is ◎ with 33 settings. But no numbers are published for distance, ball speed or dispersion, and my review has not scored it yet. I can't check it by the numbers, so it is sixth. |
Change the criteria and the order changes too. Reread it according to which criterion you look at first.
FAQ
Is the No. 1 QUANTUM ◆◆◆ right for everyone?
No. The order is what I, a golfer who averages 72, would choose for my own bag. The ◆◆◆ is a 450cc head for better players, gives little help off the center, and is sold only at select stores in Japan. If your strike wanders, start with the No. 2 GTS2. If you fight a slice, start with the No. 5 G440 K.
Should I choose the GTS2 or the GTS3?
I am still torn myself. If your strike wanders some days, or you want more height, take the GTS2. If you want the left miss gone, or prefer a compact head at address, take the GTS3. The guide for the GTS3 is a head speed of 40 m/s (about 89 mph) or more (GDO's test), so when in doubt, I think you start with the GTS2.
When is the cheapest time to buy a 2026 model?
New clubs are most expensive right after release and drop around when the next model is announced. On the used market, last year's model starts moving right after the new one is announced.
Is the latest model worth it if my head speed is slow?
Ball-speed-focused models are said to benefit players without fast head speed the most. But hitting 10 balls yourself is the surest way to know.
