Howdy, all - Long time lurker, first time poster!
Looking for some advice on bounce and grind on a few Vokey wedges.  My current iron set goes up to PW at 45* with 12* bounce.  I'm looking to pick up a 50 (as a gap wedge, primarily for full swings), a 54 (primarily for sand and perhaps some full swings) and a 58 (primarily for flops, etc near the green).  I play mostly public courses in the Midwest, where the sand is generally harder and the fairways & rough generally firmer.  My swing is more a slider / neutral (I certainly don't take large divots).  In general, I'm thinking more bounce & fuller sole on the 50 & 54, and less bounce and thinner sole on the 58.  Being in MN, I don't have much of an opportunity to demo anything on turf/sand, especially this time of year.  I'm a bit hesitant on a 54 for sand, as my understanding is that the grooves are narrower than on the 56 up, but perhaps that's a non-issue?  I could go 56/60, but have never had much luck with 60.
My current thinking goes along these lines - 50.12F, 54-10S (or 54.14F perhaps?), and 58.08M.  That said, I've been wrong twice already today!  Any advice, flaws in my logic, or other ideas are welcome, as I know just enough about this to be dangerous!
Thanks much!
