So I XC mountain bike and once in a while race (xc as well). I am looking into buying an 08 stumpjumper pro or expert and am wondering how well the '08 brain suspension system works. What are the pros and cons? Basically I am looking for a review since I cannot find one anywhere. Thanks for any and all comments on it. (note, i'm looking for info on the '08 brain. They did a big change in the technology from '07 from what I hear, so any older systems would not be very helpful.)
