golf galaxy fited me for a 910D2 12 Hi R basara shaft. Wrong! Less distance than 905R. I plan on 913D2, 9.5 R shaft. Need launch and spin rates. ques: is less or more spin better for driver? As I undertand, high KP means deloft and low spin rate; low KP means high launch and high spin rate. which is best to maximize roll-out once ball hits fairway? thank you!
