Dangerous knowledge! Someday I will have a CX bike with disc brakes and a set of road wheels/tires. A friend has a custom Ti Seven Mudhoney that she uses for everything. Hers still has cantilevers, though. I'm a HUGE fan of discs. I tried ONE ride last Winter when it was 18º...once the rims got iced-up stopping was pretty much not possible. Discs would work a lot better for Winter riding.
