The wedge is the most often used iron club for most players. Traditionally, club builders select shafts for a wedge from a normal progression in a set of shafts, usually the shaft that is incrementally shorter and stiffer than the previous longer length iron, like the 9 iron.
However, today’s golfer play specialty wedges with a variety of lofts, bounce, shape, etc. The Hi-Rev is designed to perform harmoniously with the heavier and more lofted heads to impart ball spin and preferred ball flight. Club fitters can select from three flexes and two tip configurations.
