XO Brakes For Downhill

Toxicity

one of those boys your mother warned you about
I have always run 2 pot brakes, never had issues with overheating. My CRs and 5's did fail a lot though it was not heat related...

Sounds like you have made your mind up already but I urge you to give 2012 XT trails a go, I was initially unimpressed but after a few days of riding they are incredible, still haven't bled them after cutting the lines. Am going to a Saint caliper on the front because I really think you can never have too much power.
facepalm....
