Nice. I love Hydraulics. I was riding my buddys bike with Hayes MX1 and they are crap compaired to hydros in stopping power. Not that theres anything wrong with Mechanicals. (So no one think Mech brakes are crap) Mech brakes are 100 times better then V-Brakes. Yeah I still have the 6" rotor in the back. I looked at it a while ago and I don't think theres enough room to fit a 8" there. I'll ask the LBS if the 6's just aren't performing like the 8's in front.
