I'm still using them! Cable disc brakes suck, and rim brakes are ideal for me. Cheap and effective!
I like to score my rims with sandpaper to scrub off any paint (slick stuff, why is it on a rim brake?), and make little "record grooves" for the brake shoes to bite. It helps cut squealing out, too.
Avid v-lever with twist-knob leverage adjustment (a dream come true).
My current v-brakes:
These look weird, but they have no annoying noodle! The cable nests into the longer v-brake arm, and comes out easily. Even with the 2 finger levers, I feel like I have crunching stopping power.
