im looking at three used bikes, a 06 DK slugger for $400, a 06 diamondback assault for $250, and a specialized p2 for $500 (not sure what year). The dback has a marzocchi dirtjam comp fork and the p2 has a marzocchi all mtn 1 fork as well as primo super tenderizer pedals and the slugger has a dirt jumper 1 fork and hayes disk brakes and tru vative cranks. All are in great condition. I usually ride through town doing wheelies and endos and want to start dirt jumping and riding trails. Dont know which one i should get to satisfy my needs. any suggestions?
