Why was the bounce changed on the SM6 M grind from 10 deg. on the SM5 to 8 deg. I have a 54-10 SM5 and am hesitant to change. I think that 10 deg. is a good all around bounce for a sand wedge and I like the M grind. How many of you want to hit a bunker shot with 8 deg. of bounce. If I'm wrong then I stand corrected..
