I swear this thing likes to eat my responses sometimes... yesterday I wrote in that I wanted to swap to full Rival, which includes dual-pivots, and I understand that dual-pivots require a different amount of cable pull from cantilevers, so I figured I would have to swap the brakes as well (and I think canti's look ungainly, and mine are weak, but if I can't swap them, I'll see about making them stronger; they're already very tight).
