autoFlex DRIVER SHAFT unique characteristics of make it lighter than conventional shafts with a much lower CPM. Due to the more flexible nature, a higher swing weight may cause the club head to wobble on the downswing transition. This may result in off-center impact for loss of distance and accuracy. A swing weight of D1 is found to be good for many golfers, but some have seen excellent results at D0 and even up to D3~D4 (for sf505x and xx shafts). autoFlex DRIVER SHAFT come in two colorways Pink, and Muti.
