I live and die with my short game. A function of not being long off the tee. So, for years I used one wedge for everything from 60 yards in. I won a 56 degree knock off wedge in my men's league when I was just out of school, and I already had a sand wedge, so I got a guy to bump it up to 60 degree. About 10 years ago, I started looking for a replacement. I would start the year with a new wedge, and by the 2nd month, I was selling it on ebay, and going back to the old one. Name the brand, and I probably had one in my bag at some point. Between buying and selling I was not spending a ridiculous amount of money, but I never really felt comfortable with a new wedge. I ended up with a SM6 sand wedge two years ago, when I sold the set of irons at the time, and the sand wedge went with it. I still had my 60 degree, but I started using this Vokey with low bounce. Now, I have 3 Vokey wedges in my bag, 50.8, 56.8, and a 60.4. Yesterday, they were on full display. Not exactly sure why, because I felt I was hitting decent approach shots, but I only hit 2 greens in regulation, made one birdie and 3 jacked the other one. What stood out yesterday though were my approach shots with my wedges. I got up and down 10 times for par. There were a couple good putts in there, but most of my chip shots were within 3 feet. It didn't matter how far out I was. I was hitting bump and runs with my 50, and shots just off the 2nd cut with my 60, and using the 56 for everything else.
I have not tried the SM7s. I don't think I will until these wear out. If it is not broke...
