If you ride XC changing to V's is the maddest thing ive heard in time. Unless your a hardcore racer V's are a total waste of time and money. The modulation is crap, power is crap, the pads will eat your rims. Do yourself a favour and get a set of Hope Mono Minis and relish in the joy they'll bring you everytime you ride your bike. Your brakes could save your life so why choose a crappy set of Vs? even the mechanical discs are better than v brakes so a decent set of Hopes will really blow your mind. Maelstrom mate i dont know what your on about saying he'll regret fitting a set hydro discs, do you actually ride off road? there's no comparison between Vs and hydros especially Mono Minis, so if i were you Phantom i would totally ignore the crazy advice maelstrom is spouting and get some proper brakes.
