I haven't ridden MB for a while and was getting back into the sport after I realized how awesome it was. I don't consider my self a novice, but it has been 5 or so years since I did any agressive offroad. I was going to buy either a: Specialized Rockhopper Comp Disk, or a Specialized Rockhopper Pro Disk; and use this as my base to build a XC bike from. I am currently being trained to assemble and tune bikes and have spent many hours researching on the web.
