Hi,I just played a bit with a TrackMan today, and the result was a bit "eye opening".First I tried the Shaft Optimizer with my 6 iron and it suggested Dynamic Gold X100 which I'm playing already, so that was okay.But then I went to the driver.I have always been playing a Diamana Blue 73x (the real deal, non-stock) and I started out with that. The result was:>>> Note: I have always been hitting a bit down on the ball with my driver <<<Titleist 913D3 9.5° with Diamana Blue 73x-stishaft and Pro V1xAverage results over 10 shotsA-1 and B-2 but there were not really a difference with my carry and and Smash Fact.
Then I tried the new driver from another manufacturer with a MRC KURO KATE SILVER 60 S-FlexAverage result over 10 shotsSetting Neutral 9.5°
Same club speed but more ball speed?I know I was not testing all settings, so the results can't be 100%, since there might be a better setting for me with the Titleist 913D3, but I got
with the other driver with same swing and ONLY a S-Flex shaft, and my swing speed was almost the same?I had big eyes, and it hurt my Titleist heart.Was the club-head (technology) better for me with the other driver, or is the Diamana Blue 73 X-Stiff too stiff or heavy for me? It shouldn't be with my 115 club speed, or what do you guys think?I don't know if I can get a stock-shaft to my 913D3 that can perform better for me?Any ideas?I don't have the full TrackMan data, but I can try and get it if it was saved.
Chris - you ask some good questions here. I have that KK driver in some of my fitting carts. let me get some specs and compare it for you and I will get back to you soon.

The vendor's rating of R, S, X is only a guide. There are no standards. Most other drivers have a stock 45.75 inch shaft. Just as an example, I gained yardage hitting into a net with a Trackman just switching between R shafts Bassara 50 g to the Blue shaft 62 g on a 913 D2. This was due to smash factor from 1.4 to 1.5 and a lower spin. Obviously, your results will vary. I'd let a fitter work with my swing and optimize launch and trajectory without deciding on weight and flex before starting the process. I think your only conclusion now is your current shaft may not be optimal.
