I'm looking at a few different bikes,all around 5" travel, particularly the Rocky mountain ETSX, YETI 575, and possibly the Blurs. How does the FSR 120 fit in/compare with the rest of these? im mostly a XC rider, currently on a schwinn rocket 88, so any of these bikes will be a step up in travel. i put a lot of emphasis on weight and climbing ability. Dont really do any drops or anything like that. I've heard good reviews of the high end FSR 120, especially with the brain. what about slightly lower end models without the brain? i would probably buy a new or used frame, then build it up myself.
