I have a Vokey SM4 58-09 that I absolutely love. The wedge recently just got a huge gouge in it from a rock. I am looking at a new Vokey, I noticed that the SM6 don't carry the 58-09 it is the M grind 58-08 and S grind 58-10. I know I will probably get fitted, however I was curious about which was similar to my old SM4 58-09. Thanks for your participation
