Duke - I'm 64 with 85-86 mph driver swing. Although I strike my irons in the same spot, I hit all over the face of my driver causing inconsistent distance and dispersion. I had a fitter put me into a counter balanced shaft and improved my strike immediately (and added 20+ yards). The problem was the low kick point of my old shaft did not match my swing tempo. I happen to have the Evenflow Riptide Blue 5.5 Reg but there are many similar counterbalanced shafts available.
