Considering all stiff flex, what's different about the following three shafts. TT DG S300 (Std), KBS, projectx 6.0. A fitter at a retail store told me the DG S300 are meant to keep the ball flight lower. The KBS would create a higher ball flight. He didn't say anything about the proj x 6.0. Anyone with knowledge please help as I am trying to make. My final decision soon. Cathi or Cameron I would like to hear the manufacturers thoughts as well since you chose the s300 as the standard shaft. Any plusses or minuses to the three in questio? Thanks
