A similar question was thrown out a while back with no answer as well...seems like there aren't many playing these...I have a regular 588 51* gap wedge I still use and it is a great club...I also have two sm 56 and 60 and will probably replace the cleveland with a vokey because the others are that good...even thinking about changing out the pitching wedge...
yeah, i have a spin milled 58 and will probably get a 54 sandwedge (spin milled)...i was just curious as to what people thought about the 588s. they seem to be pretty much the same...oh well, i'm sticking to my titleists...
