I love my Avid mechanical discs, and they aren't any more confusing/hard to deal with than V-brakes. Great for mud. Great for long tough downhills. After riding Black Mountain in NC, and having my forearms dying from lactic acid on the descent, I knew discs were the way to go on the next bike.
I went from HT to FS, and I love my bike, Titus Locomoto, but he's kind of heavy. I would probably take that more into consideration on a next bike.
