This is kinda a double post (apologies), but I'd like some feedback concerning using '08 XTR calipers/levers with 203mm XT rotors. I have not had experience with Shimano brakes since the old (and awesome) XT discs... I have had experience with Avid's '04 Juicy 7s. Great stopping power, but a bit unreliable. My mate swears by his Saint brakes, saying he would like to try the '08 XTRs (same price as Saint). I wouldn't mind the new Juicy Carbons, but basically to match up with the SRAM build. But brand-matching is not a good enough reason to choose a hugely important component for a race bike... Anyone tried the new XTR braking systems for DH use? What would be your ultimate DH race brake system?
