I have played The AP2's for several years and am ready to order the new AP2 712's. I am currently playing the KBS tour shaft at 1/2 inch long and 1*flat from the Titleist standard + 1*strong to help control ball flight. At 60 years old I need to play a softer shaft and am considering either the Project X 5.5 or the Nippon 105 or 970. Please let me know your thoughts as I am ready to place the order. BC
