can any one help me pick which onr to get? I do down hill and urban with some jumps. right now i have a 5-5 bike a giant warp with manitou black and dh wheels (really solid) i have done 7" to flat and dont want to break any thing by doing bigger stuff. I like the 1.5 head set on the asx plus the linkage looks like it will make the rear end more solid. but i have seen the guys at the red bull rampage doing huge air on the bullit. two more things... first I have found that guys that ride the bullit are pricks (so far) and that Im 15 and will have to work hard for this bike I want it to be the right choice... thanks for any sugestions.
