Swing Speed and Shaft Flex

[beck9965]

I'm low/mid 70's with a 6 iron which I recon outs me low to mid 80's with the driver(?).

I have a Graphite Design Tour AD YSQ in stiff in my driver and a regular flex stock Kai'li shaft in my fairway woods.

I doubt the regular flex, plays remotely to the same flex as the YSQ, yet I still hit both well enough.

Completely wrong based on my swing speed.

Yet, I'm consistently longer with this shaft in my driver over the stock regular flex Kai'li I had previously.

As I say, completely the wrong shaft based on swing speed alone, but it seems to suit me.

Perhaps there is something else in my swing that makes it suit.

My driver swing speed was 101mph last time I got fitted, after several shaft changes I ended up with a Graphite Design ys6 in a stiff and this was mainly due to the transition in my swing from top to downswing, I have smooth transition apparently so this was the shaft that suited my swing speed the Project X came a close second but the dispersion on the ys6 was better it also gave me an extra 40 yards, I also tried a softer shaft that turned out terrible, the fitting was with a Titleist technician at The Celtic Manor, I also trie the same shaft that Rory had in his driver at the time, a bit of fun the Titleist guy said, that wasn't too bad either.
