Need the help of Team Titleist - My driver swing speed ranges from 88 - 90 mph with a spin rate of 1800 - 2000 rpm using the 913D2 with Titleist Bassara stock regular flex shaft. A1 setting produces the best results from Trackman outdoors. Are there any other shaft recommendations to increase spin, other than potentially an A flex in the same shaft?
For reference, I am a relatively short distance player and play to a low single digit handicap playing in lots of tournaments competing favorably (short game is my strength) - ideally, I would like a little more carry.
