When you go through a fitting for your driver, we optimize your launch angle, spin rate, and shot dispersion so that you can hit the longest straightest drives. The mantra of fitting for drivers is high launch and low spin, so we try to optimize both of these fitting attributes. But certain golfers deliver the club head to the ball in such a manner that they create low launch and high spin. This can be caused by hitting down on the ball with the driver (negative attack angle) or hitting on the bottom of the club face. While it is sometimes difficult to change a golfer’s swing, getting these two issues corrected will dramatically improve distance. But if I had to choose one over the other, I would optimize launch angle first, and then work on other factors (shaft, ball, club head) that can bring down spin rates.
