Anyone using these? Reviews, cons, pros?

Obviously I can't ride fast if I don't have Hipers, strokin.gif (j/k Hiper fanatics!) but I'm just trying to get some info about other possible options. Guys were bending metal wheels and breaking their Hipers all day yesterday, and I have no problem sacrificing some weight for durabiltiy.

Thanks.......Bill

Ooops, my bad. I have no idea why it's in this section.
