After much deliberation, I put an SM7-54.10S in the bag yesterday. It's replacing an old TM RAC 56 degree.I spent more than an hour at my local PGA Superstore, trying to decide between the S grind and the M grind.I brought my old wedge with me and compared camber,shape, bounce etc. The look at dress is similar, but the Vokey has a cleaner look. Comparing the sole,the SM7 is very similar to what I'm replacing, which helped in my decision. I really liked the grind of the trailing edge. I've got a 58.08M in the bag, so the gapping with the addition of the 54 is much better.
