I have the Spin-Milled c-c 54-11 that I bent to 55-12 and it is (more or less) my all around short game club. I'm not one to do full golf shots with my 54 and 62 unless absolutely necessary (I'll hir a pitch with my 9 iron or a choke 50 full shot instead of a full shot with the 54 or a pitch with 50 or 54 instead of full shot with 62); less work that way. I used to carry the Spin-Milled 64-07 and it had 7* effective bounce but I used it primarily for short bunker shots and grassy lie shots to a tight pin. For Titleist - what grind is on the sole. The specs say the SM4 54-11 has 11* effective bounce. That means maybe the leading edge may have 15* bounce (Titleist???). This wedge would work great in soft sand and grassy lies but you may have to deloft a little on fairway shots. If your intent is only full swing shots then the 54-08 may be a better choice. You can bend it to 55 and have 9* bounce (which works on long bunker shots in soft sand). My experience with composite grind soles is the Cleveland CG15 DSG 58 and 64 and the Vokey Spin-Milled 64-07. The only issue I had was hitting off tight lies so I switched to a 60-07; however, its shortcoming was hitting high bunker shots in soft sand. I replaced the 60-07 and 64-07 with a 62-07 (which has a full sole but with a wide flange) and it works well in all short range conditions. Have you ever thought about getting a 50-08 and replacing the 48 and the 52 with it? I didn't like the 48 because it was a bit long for me as far as wedges are concerned. I bent my 50 to 51. I love this wedge to death (also my 9 iron has a 45* loft).
