x20 callway iron shaft question?

Re: x20 callway iron shaft question?

X20 clubhead designed for high ball flight, and Uniflex has midkick (mid flex) for moderate ball height. Short irons are borderline "too high" into wind, but shots seem to hold line fairly well in crosswinds.

Uniflex designed to bridge R and S flex; on faster swings it functions as S, on slower or partial swings functions as R. (It's magic, I guess.)

In initial testing, a clubfitter suggested I might want to try DG SL (superlite) R300 shaft - it has high kickpoint -> lower ball flight, and would work against the higher loft design of head. You might consider a DG S300 - what you have on your Mizunos.

Also, consider the X22 Tour clubs: a medium-high trajectory clubhead... it has a slightly higher Vertical Center of Gravity, which means you could better hit knock-downs when needed. (Yes, higher VCOG means lower ball flight; less pop-up from clubhead.) Depends on your trajectory plan, and whether you want straight-ball or work the ball. You can work the ball some with the X20/X22 models, but it's easier to work with the Tour models.

Re: x20 callway iron shaft question?

The X20s are game improvement irons, the MP-32s are players irons.

Game Improvement irons (GI) are designed for less experienced and high handicap players. They have a low, rearward center of gravity, and are designed to hit the ball high. This is because high handicappers have trouble getting the ball airborne. Uniflex shafts are basic shafts put on game improvement irons, they hit the ball high, and are good quality. These two factors (center of gravity and shaft flex/kick) combined mean that with a high swing speed and a good, solid strike, you'll hit it to the moon.

MP-32s are players irons, minimal offset, less forgiving, and a higher center of gravity right behind the face. These are designed to be workable, so you can hit it high, low, left, right, etc. The dynamic golf S300 shaft is a much stiffer, precision made shaft that is used on higher end clubs. It's designed to launch the ball much lower than a uniflex.

I personally play True Temper Speed Step shafts. They are stiff flex, and very solid with a higher kick point. My irons are Nike forged Pro Combo irons, PW-8 are blades, 7-5 are Split cavity, and 4 and 3 are full cavities. They have no offset, and a very high center of gravity.



The difference between these and my Adams Tight Lies GI irons is quite stunning. The Adams 3 iron goes as high as the Nike PW, in both cases, very high. I launch the ball exceptionally high as it is, but still like S flex shafts in my irons instead of X (something about the softness I like). I can hit a 2 iron as high as most people can hit an 8 iron, but at the same time, I know how to flight it down as well. Learning to do this is a major part of getting better. You can hit the Callaways low, it's just a matter of knowing how. For that, I'd suggest you lookup the knockdown shot.

Re: x20 callway iron shaft question?

They hit the ball high depends on which Unfilex flavor Callaway puts into the club. Callaway Golf Uniflex X-20 Steel (circa 2008) had mid kickpoint = moderate trajectory from shaft. Big Bertha Uniflex Steel (BB '08) has low kickpoint = high trajectory from shaft. For 2009, the stock X-22 shaft was the True Temper High Launch Uniflex. Despite HL tag, it is still listed as having a mid kickpoint.
This info is from the Callaway Pocket Reference Guide, 2008 and 2009 editions.

So, a Callaway X-20 w/Uniflex hits the ball fairly high, the BB w/Uniflex hits the ball really high. Also, I suspect you generate much greater clubhead speed than I do. Thus, you would hit the ball higher with an X-20 Uniflex than I can. The S300 shafts you mention have a high kickpoint, which would help you keep the ball down.
Hitting knockdowns can be tough if both clubhead and shaft flip the ball high into the air.

Also, solid comparison on the MP-32, Nike and Adams clubs. I have rarely hit any of those lines, and your info shows where their different club modesl fit in. (I recognize that Mizuno irons are top-notch clubs, I just don't have much experience with them.)

Re: x20 callway iron shaft question?

Oh, really? I always thought that "uniflex" were homogeneous. I mean, "uni" = 1. I had no idea there were different uniflex models. My Adams w/ Uniflex were probably meant to hit the ball even higher. They were quite soft, but they did have a nice feel.

True, but it's cheaper!
