Par4QC Nat I think, for us newbies, you may need to show a pic of the OG grip. 😉😄 That said, I do like the black a little better than the b/w. Main reason is the black can always be found cheaper.
Nat bad9 Jeff cole said the same thing - the black is slightly softer. But I just asked Jim Y at Golfworks and he said they are the exact same. Since I want a 580 ribbed, and don't want to do my own ribs, I'll give the white fill OG a go
