+1 on the Schwalbes. I have Fat Alberts, but i'm running a Schwalbe Nobbie Nick on the front and Schwalbe Rocket Ron on the back. I think the Rocket Ron at 2.25 is thin right now on the back for my riding style and am thinking about going back to a Fat Albert 2.35 on the rear. My buddies all ride various Schwalbe's (Hans Dampf, Nicks, Ralphs, etc) and have all had good luck with them around here and out West.
