I swapped from Oryx to CR720s for: ease of setup, cartridge pad holders, squeal reduction, and looks. I was gonna have to buy pads for the Oryx anyway, and the CR720s are more punkrock.

If you want the easier-to-adjust-ever cantis, score some Onzas. I will forever regret only buying a rear brake...and eventually selling it on a gorgeous MB-1 for next to nothing.
