By low bounce, i mean 6-7 degrees or so - but to me, bounce is only a starting point/number - I look at where the bounce is cut off - look at Edel - they make a high initial bounce at the middle and leading edge and then cut off that medium sole bounce with trailing, toe and heel relief. They have an 18 deg bounce wedge to get the initial slide but so much relief that it plays with great versatility from tight lies. Not as great from soft sand because it effectively turns a medium sole into an almost narrow sole with all that relief - so you've really got to hit the back of the sole first into the sand first to get glideI know there are extreme specs for wedges suitable for very few (if any) players. The former Merit Zero Bounce wedge company products increased customer scoring averages by 3 to 5 shots per round.
For most amateurs, as TIger and Jason Day on a video I saw, both say - no regular Joe should have less than 12 degrees of bounce. Well, I don't know about that - you can have a Ping Eye 2 grind with 8 bounce and a wide sole, and it glides well (more effective bounce), plays from the bunker great and somehow still offers great versatility on tight conditiions. Probably the best wedge grind for a sand wedge for most of us; or an M type grind with 12 bounce and medium width and limited heel, toe, trailing edge grind (but with little trailing edge relief, not as versatile). But the Eye 2 (or PM grind) - now that is a grind for the masses.
