Yeah fietsbob and bianchigirll I'm still on the fence as to running discs or cantis. . . in my experience, both have plenty of stopping power (a plus), both allow lots of space for fenders/big tires (another plus), but both are finicky in their own way. I like the idea of setting up some light xc-style wheels with deep Vs and disc hubs, but I also like the idea of running cantis and NOT having to listen to the whirrrr of discs all the time. Plus cantis are a bit more under the radar (less thieve-worthy, which is a big enough problem to hold in consideration around these parts. . .).

If I do run cantis, I figured I'd throw a stiffener on at least the fork (ala Paul's brake booster). Bianchigirll, you say don't go carbon if you're using cantis? por que?
