I did an interesting test the other day at Golfsmith. I hit a 12* Taylormade SLDR mini (260cc), and 13.5* Titleist 913Fd (180cc) and a 10.5* Titleist 913D2 (460cc). They were all stiff shaft. I hit the Taylormade first and it felt pretty good with a slight draw. The head felt fairly easy to control but the sound was a little dead to me at impact. I was carrying about 200 with it.
Then on to the 913Fd. This one I was carrying about 205. Nice crisp sound at impact. The head felt easy to control. Hmm, maybe there is something to this.
Then finally the 913D2. Carry 220 with a 10.5 degree head. My launch angle was a little low, 12 degrees. I currently use a 12 degree 910D2. Side by side, the head did not feel any harder to control. Shot dispersion was the same as the others but with 15 more yards. This is obviously due to the shaft length and COR of the driver face. they did not have a 12 deg to try.
So bottom line, I think the "difficulty" with controlling the driver is in my head more that in the club. I recommend others try this and report back what they find.
