Iron Fitting, Best fit came out with lowest ball speed What gives.

[juicegoose]

So I've been itching for some irons lately. Been playing the same JPX 800 pros in G95 s300 stiff shafts since i really got into golf. Bought them new when they came on the market many years ago.

Decided to go to my local pgasuperstore and do an iron fitting on the gcQuad. Pretty good experience overall and the guy was super knowledgeable. I really just went in to see shaft wise and iron wise what felt good. Mizuno shaft optimizer was used as well.

I'll post the results of the 2 contenders below. 

The club I seem to hit the best or at least felt the best hitting was the T100s with KBS C taper lite shaft(110 s). It was the first club that i actually had the wow moment.  Misses seemed to be baby draws or baby fades. Some irons were all over the place even though shaft was the same. Problem is that overall my ball speed was down by about 7 mph and carry and overall distance average was down 5-7 too. But when comparing a single line with similar ball speed the numbers were dang near identical.

 

Could this be from fatigue only? We did get to the t100 later in the session and the final version shown as 2 degrees up was the last thing we tried.

 

 

As you can see the jpx 921 forged(2nd club we tested) in same shaft had better ball speed and distance numbers although the misses seemed more pronounced then with t100s and i struggled on side spin.

 

As you can see my offline was the best with the t100s as well.

 

I'm not chasing distance in any way but would hate to get into a club that is a degree stronger then my old set and produces similar characteristics in all areas except for ball speed and distance. 

 

I'm going back for a free followup with fresh arms but i'm just curious on the numbers game. 

 

Thanks folks

Based on the launch angles, the ball speed difference could partly be because of delivering the club with a bit more dynamic loft.    How much of that is from the static lofts and how much from a change in delivery (swing weight, shaft weight and stiffness can all influence the delivery) we can't say since there was no club data collected.

 

You should have been checking ball impact location on the face.   How did the different shafts effect the location and consistency of the face impact?   That can have a big influence on ball speed.

 

If you were feeling fatigued that could be an issue as well but without club head speed, it's impossible to say how much that might have been a factor.

 

Did the demo clubs have the same sized grip as your set?

 

Given it was the PGASS - I'm guessing they didn't do anything to check/compare or fit swing weight?   So the clubs could have been all over the place and for some that can potentially have a significant influence on the delivery and results.

Thanks for the reply stuart. Fit was done with a gcquad so club head and swing data was captured. The report sent simply didn't have that information in it. I will ask for another report with that data if possible. The clubs didn't have my exact grip. All had standard tour velvet. I play tour velvet with the +4.  you are correct we didn't check swing weight. that is something I will keep in mind in the followup.
