Went to Golf Galaxy for a fitting. Ended up ordering the M5 9 degree turned up to 10.5, Regular flex Project X, 5.5, Evenflow Max Carry 45 shaft, with the Golf Pride Stock Grip. I am replacing a R15 and increased my swing speed by 5 mph, decreased spin by 1500 and the most important thing, increased total distance by 20-25 yds. If those numbers hold up on the course I will be one VERY happy golfer. Now if that dang club will just get here!
