I have recently upgraded to the SM 7 wedges after purchasing a set of AP3 irons. I only changed due to the gaps between my previous wedges and the PW being much stronger. The weather has not been great over the last month or so, and the course has been wet so the wedges were just stopping dead. This week it was different, the greens had firmed up enough to really test the wedges. I could not believe the amount of spin I was able to get, even with half shots. Although I am still getting to grips with the yardages, I can see that this spring I should be dialing in yardages perfectly with these SM 7 wedges.
