I just wanted to clarify...my comment about rims being better because they force you (well, me anyway) to stay on top of truing was more about acknowledging my personal foibles than a blanket statement. I guess what I meant was, "I prefer rims to discs because they discourage me from getting lazy about wheel truing, which I suspect is what would happen if I ran discs."

I've ridden on plenty of bikes with discs, though, and find them an aesthetically superior choice to rim brakes, in much the same way that a Lotus 7 would be an aesthetically superior choice to a pickup truck for driving a twisty back road.

Both'll get you where you're going, though.
