The new Vokey SM5s are great wedges and the 60 degree comes in th following:

60.04 L grind

60.07 S grind

60.08 M grind

60.11 K grind

The SM5 finishs come in the tour chrome, gold nickel and raw black......

Which one should you buy?  Go see a fitter and let a professional help you make that determination.  Hit a few and see what feels best....you might like the standard shaft and you might want to get the shaft to match the shafts in you current set of clubs...regardless get fitted by a professional.....cheers

Depends how you use it, but yes, get fitted. 

I use the 60.08M grind. I like to open the face and this grind I was told, is better for that. I like some bounce, but not too much and this is perfect for me. i did also match my shafts and lie angle to my irons.
