Mine is a stainless I bought off some guy here on the boards. It's a lesser known name which escapes me right now. I'd say they hole shot is a bit better, but I think some of the stuff OJ and Acme are doing now with a 3 blade is just as good if not better.

To be honest I'm thinking of going back to the 3 blade and trying one like Z got for his LS as I ski every morning usually and my boat is one of 3 in the rotation, while my kids are still pretty young and don't require anything special to have fun.
