Hi, I am planning on buying a mod for the first time - going with the ZOO! Python (prob around xmas time) I just wanted to know your thoughts on what is best - front hydraulic disc or HS33? I will have an HS33 on the back. If it's a disc it will prb be a magura Marta or whatever they are called. So don't mention avid mechanicals etc The thing I worry about with a disc is knocking it on stuff - do you find that to be a problem? Also what about weight? thanks, Nick.
