hydraulic disc brakes are amazing! i was a bit skeptical at first, but after owning a bike equipped with them for a year now, i too worship at the church of disc.

for wet, gloppy, sloppy, snowy, slushy, icy, dirty, messy, filthy winter riding, disc brakes simply work much better than any rim brake set-up i've used (caliper, canti, and v-brake).
