werd with what manuel said, 48ep is so good, any less feels like a violation, i've tried a bike with the original XC pro2 and it felt pretty lacking, but i'm a heavy guy and i do put a fair shunt through my gear, it depends what type of riding you plan on doing too i guess, if your gona be using alot of static moves, sidehops, pedal hops, etc then you'll be much happier with the trials dedicated one, but if you're all about rolling and flowing you could probably get away with it...
