I am looking to purchase a 910 d3 in 8.5 degrees of loft. I am looking for opinions on what shaft would fit me. For years I competed in long drive and played my rounds of golf with a 50 inch xxx driver with about 5.5 to 6 degrees of loft.  My club head speed averages around upper 130's to low 140's.  I have no doubt when playing I will not be swinging out of my shoes however I would like something that will hold up if i decide to take a rip at one on a par 5.   Any advice would be appreciated.
