i am switching from V-brakes (XTR) to disc and was wondering which set would fit my needs the best. I need it for aggressive XC, will be installed on Ellsworth Truth w/ Fox F100X and 5th Element. I often race 24 hours events.

Reason for switching is braking power. I am 205# and want to brake as late as possible during the race. V-brakes failed me couple of times. Also, wet braking is a bit of a concern.

As a V-brake user, I'd prefer as less maintenance as possible, but if the difference in performance is so significant, I am not afraid of rolling the sleeves and bleeding and adjusting the system to death (I am pretty skilled technically). I just dont want the system that I will have to bleed in the middle of the race...

thanks for your input...
