55 gram shafts would play pretty soft, and they would defnetly be lighter than ANY steel shaft out there...draw biased irons would most likely draw the ball in the hands of many players...add to the mix the extra length found in many graphite shafts sets across the board when compared to standard lenght steel shafts as well as the strong lofts of the r7 irons, I bet that they send the ball out there a long way, have active tips that help get the ball up and would find lots of support for those two attributes in the minds of many golfers...
