Ditto what Ed said about metal wheels. The only one I have is a 1/4" that I don't know if I've ever even used. I think I got it to clean up choils and such. I doubt it could even be rubberized at that diameter.
I feel the same way about plattens, on which I've shredded numerous belts. I use them because the rubber rolling platen is outside my financial means at the moment (and most moments). At least with metal wheels, they are moving with the belt--less friction on the cloth--maybe? In theory?
I don't do any significant stock removal against a platen, and I never use one at full speed.
