Traded in my old SM -5 wedges (56 & 52) for SM - 7 wedges (50 & 56). The 56 has a swing weight od D5 which is much heavier than my older 56 SM-5 wedge. Was going to get the SM-8 60 to replace my SM-5 60 degree but notices it is also a D% swing weight. Is there a way to get the weight at a D2 & how could I get the swing weight on my 56 SM-7 to a D2 weight.
