Best Irons for a Penetrating FlightFrom measured launch angle, spin and max height, I picked five that are lifted by spin

Updated: Oct 1, 2026Contains affiliate links

The same person swings a 7-iron at about the same speed. Even so, launch angle differed by as much as 3° depending on the iron, from the 18° range to the 21° range.
It launches low and is lifted by the lift from backspin. That is a rising, penetrating iron shot (I wrote up the mechanism in How to Hit a Penetrating Iron Flight). This article ranks the irons that posted numbers close to that shape. As a nerd who studies golf gear, I picked five from measured launch angle, spin, max height, land angle and ball speed. Where a club is good, I praise it without holding back. Where it is so-so, I say so-so.

Bottom line

I Ranked Them by How Many Times Their No-Air Height They Climbed

How do you measure a rising, penetrating shot in numbers? I made one yardstick.

If you know the ball speed and launch angle, you can calculate the height the ball would reach with no air (the vacuum height). Divide the actual max height by that height. The larger this multiple, the larger the share that was lifted by the lift from spin. In other words, the ball is rising and penetrating (in this article I call it the "lift ratio." It is my calculation).

For a PGA Tour player's 7-iron, this lift ratio was about 2.6x. A ball that would reach about 12 m with no air climbs to 31 m.

On top of that, I looked at five criteria.

• Launch angle: the lower, the closer to the shape of a penetrating flight
• Spin: the more, the greater the lift
• Max height and lift ratio: how far spin lifted the ball
• Land angle: the larger, the better it stops on the green
• Ball speed: even if it penetrates, a slow ball does not go far

The measured numbers come from the TrackMan measurements on masa-golf, an individual's site in Japan. They are with a 7-iron, at a head speed of 37–39 m/s, with the same brand of ball. I narrowed the field to irons with a 7-iron loft of 31° or more, because the stronger the loft, the less spin, and the less likely the ball is to be lifted by spin.

The Five by Launch Angle, Spin and Lift Ratio

Launch angle, spin, max height, land angle and ball speed are TrackMan 4 measurements by masa-golf (7-iron, averages). Max height is converted from yards to meters. "Height with no air" and "lift ratio" are my calculations from ball speed and launch angle. ◎ marks the best value among the five. Head speed differs slightly: 38.9 m/s for the 100CB, 38.7 m/s for the ZXi7, and 37.4–37.7 m/s for the other three. Lofts are each maker's official figures (for the P7CB, the figure given in the test article).

The average for the irons the same site has measured is a 19.7° launch and 6,143 rpm of spin. The top three launch lower than average. The bottom two launch higher than average and spin more than average. Both "take spin," but the shape of the flight is different.

Why This Order

The reasons are written only from the numbers in this article and the official specs. This is not a sales ranking.

A low launch, and a lot of spin. I looked first at whether an iron had both. Change the criteria and the order changes too. Reread it according to which criterion you look at first.

No. 1 to No. 5: praise and weak spots

No. 1 TaylorMade P7CB (2024). Launches low and spins the most.

Launch is 18.7°. Low. Spin is 6,793 rpm. High. A low launch and a lot of spin are showing up at the same time. Normally these two are a trade-off. Strengthen the loft and it launches lower but spin drops; weaken it and spin rises but it launches higher. The P7CB's 7-iron is a weak 33°, yet it launches in the 18° range. That is what is so impressive about this one.

The lift ratio is 2.05x. A ball that would reach 13.5 m with no air climbed to 27.6 m.

There are three so-so points. First, distance. Carry is 153.9 yards, on the short side among the five. The land angle is 48.2°, smaller than the same site's average (49.2°). And I have not been able to confirm the loft and price on the official Japanese site. The 33° is the figure given in the test article.

Great for you if you

• Your ball climbs too high and loses to the wind
• You want to hit a chosen height more than you want distance
• You like forged soft-carbon-steel cavity backs

Better to skip if you

• You want 10 more yards from your 7-iron (that is No. 2)
• Your strike point scatters up and down (the spin numbers will not be consistent)

No. 2 Bridgestone B-FORGED 100CB. It penetrates, and it goes far.

The lift ratio is 2.03x, almost the same as the P7CB. On top of that, its 52.5 m/s ball speed and 163.7 yards of carry are the best of the five. A penetrating flight without giving up distance. This is the only one that answers both. It is a current model that only came out in September 2026, and the 7-iron is 32°. It is a one-piece cavity back forged from soft carbon steel.

I will write the so-so points too. Spin is 6,064 rpm. That is about the same as the same site's average (6,143 rpm) and 729 rpm lower than the P7CB. Also, the head speed in the test was 38.9 m/s, faster than the P7CB's 37.7 m/s. Part of the gap in ball speed and carry comes from that.

Great for you if you

• You want a penetrating flight but do not want to lose distance per club
• You want to play the newest model
• You are moving from irons with a 7-iron loft of around 32°

Better to skip if you

• You want to stop the ball with spin above all (that is No. 1 or No. 4)

I cover the differences between the 100CB and the hollow-body 200CB+ in B-FORGED 100CB vs 200CB+.

No. 3 Bridgestone 242CB+. The biggest lift ratio.

Its 18.2° launch is the lowest of the five, and its 2.10x lift ratio is the largest. On the shape of a penetrating flight alone, this is No. 1. It is a previous-generation model released in September 2024, and the list price for a 6-piece set was ¥145,200. Prices have now come down even for new sets (see the price box below).

The reason I put it at No. 3 is height. Max height 27.2 m, land angle 47.3°. Both are the smallest of the five. It penetrates, but it does not come down steeply. This part is so-so. For someone who wants to stop the ball on firm greens, it may not be enough. The 7-iron is 31°, the strongest loft among the five.

Great for you if you

• You want a low, strong ball that keeps your distances consistent on windy days
• You want to buy a previous-generation model cheaply

Better to skip if you

• Your problem is the ball not stopping on the green (that is No. 4 or No. 5)

No. 4 Titleist T100 (2025). Second for spin. But it launches high.

Its 6,667 rpm of spin is second only to the P7CB. Its land angle is 50.4° too. It stops. For a ball that stops, it ranks above the 3 irons above it. The 7-iron is 33°, and the official 6-piece set is ¥178,200.

The reason I put it at No. 4 is launch angle. At 20.7°, it is 2° higher than the P7CB. Its lift ratio stays at 1.87x. Rather than being lifted by spin, it is a ball that launches high from the start. Its 50.2 m/s ball speed and 152.3 yards of carry are the smallest of the five. This is a so-so point too.

Great for you if you

• You would rather have the ball stop on the green than penetrate
• Your woods and wedges are all Titleist

Better to skip if you

• You do not want to lose 7-iron distance
• Your high ball gets pushed around by the wind

I summarize the differences from the previous model in T100 Irons: 2023 vs 2025 Model.

No. 5 Srixon ZXi7 (2026). The best height and land angle.

It is high. Max height 33.1 m, land angle 51.8°. Both are the best of the five. It also has 6,388 rpm of spin, and its ball speed is a fast 52.2 m/s. It climbs high and stops from above. For an iron, these are very good numbers. The 7-iron is 32°, and a 6-piece set is ¥171,600.

Even so, it is No. 5 because the yardstick in this article is a rising, penetrating shot. Its 20.9° launch is the highest of the five, and its lift ratio is 1.87x. It is not a ball that launches low and penetrates, but one that launches high and climbs high. In a ranking of balls that stop, the order would be reversed.

Great for you if you

• You want to stop the ball with height
• You hit down and take long divots

Better to skip if you

• You want a ball that launches low (that is the top three)

I wrote about choosing between it and the ZXi5 in ZXi5 vs ZXi7.

The Numbers for Three That Missed the Five

I will also list the irons I considered but left out of the ranking.

• Titleist T250: its 2.11x lift ratio is the largest of everything I calculated this time. Launch 18.3°, ball speed 52.1 m/s. But its 7-iron is 30.5°, short of the 31° cutoff. Its spin is also 6,020 rpm, below average.
• Titleist T150 (2025): lift ratio 1.88x, spin 6,325 rpm. Almost the same shape as the T100. I put the T100, which spins 342 rpm more, in the ranking.
• Srixon ZXi5 (2026): spin 6,660 rpm, max height 35.7 m, land angle 53.4°. Its height and stopping power are the best of everything I looked at this time. But its launch is 21.2°. It is not a ball that penetrates, but one that climbs high.

What to check for ¥0 before you buy

Even if you change irons, the ball will not penetrate unless your strike changes. First, look at two things with your current 7-iron.

1. Launch angle. At a range or big retailer with a launch monitor, hit 10 balls with your 7-iron. The five in the table above launch at 18–21°. If yours launches much higher than that, you are adding loft at impact. The strike comes before the equipment.
2. Grooves. If they are packed with dirt, clean them with a brush. That alone brings some spin back.

I wrote about the strike itself in How to Hit a Penetrating Iron Flight. Less loft, from above, slightly below center. Those three.
