Clay,
I know your're trying to save a buck. Let me put my two pennies into the jar and do what you will with it. I have tried all the options of screw in studs except for the motorcross ones in the previous link. The sheet metal screws are ok. the Simms studs without the carbide pieces are better, and the Simms studs with the carbide pieces are the best. Ok, better, best meaning gripping power and wear. If I was fishing and heavy currents in a slick bottomed river, I'd want the Simms with the carbide. I really feel that they made that much of a difference.
