which shaft - hi I have a 910fd 13.5 3 wood with a reg kali shaft in c2 position and i hit it miles. I cant seem to get the same results from my d2 driver 9.5 with stiff kali shaft irrespective what setting i put it in. do i need a different shaft? I hit a high ball generally but have superb ball flight with the 910 fd 3 wood
