I had the opportunity of test driving the R11 and the 910D2. Both in Regular and Stiff Shaft. I hit the R11 further in the Regular than both of the 910D2. But! Always have to have a but! Man I was sooo accurate with the Titleist. Other issue is the R11 was a 10.5 and the 910 was 9.5. The Titleist Shafts used were the Kai' Li.
Golf Galaxy didn't provide me the launch numbers etc but said my swing speed was mid 90's.
Going by feel.. I chose the Regular shaft. I felt I got more pop on the ball and definitely more Distance. Dispersion seemed very good.
I'm just worried I should have bought Stiff. My last driver was a Cleveland XL270 and while I mashed it sometimes, was not very accurate with it. I compared torque specs on both and the Cleveland is 6.4 compared to the 5.0 of the Regular Kai Li.
I would have loved to have been properly fitted and probably over the winter I may have time to do so while the kids are in school. If all else fails I can swap out with the companies 30 day playability program. But I think the Kai Li Regular will be fine. Please tell me I didn't make the wrong decision.
