if any of you guys can wait theres' an Avid ultimate canti coming out that switches between low profile and high profile to advantage cyclocross racers... for gunky races set them high profile and far out for better mud clearance, for dry races set them tight in low profile for better power..

I've not personally been happy with the avid cantis but their shortys are radically redesigned this year and haven't tried the new versions yet. probably won't as the Shimano's are stout.
