I got driver fitted by my club pro who is a great instructor and fitter. We went through many driver brands and shafts and my best fit was the 917D2. With the Diamana Blue 60 S shaft, I was spot on in spin rate and launch and I was longer with this driver than any other brand I tried. Dispersion was also the tightest with the D2 which is critical since my home course is quite narrow on many holes. The fitter had me hit 10 shots with every driver-shaft combo as part of the fitting process and the fitting took almost 90 minutes. My numbers with the 917D2 came out to 14.8 launch angle average, 2011 RPM spin, 146 ball speed, smash of 1.52, and spin loft of 11.1 degrees. Great for me at age 60. The club had to be ordered so I am looking forward to receiving it soon.
