first off the speedbump has insane CAMBER not ROCKER the whole idea is that it would springy as shit so you could get mad boost. the only prob i see is that switch ups or spinning out the ski would catch who knows.
next is the backseat pro. basically tons of rocker plus backseat mount allows you to ride over anything especially gapers.
finally the holy ski. this i s ahomage to the line reactor where the whole ski has preloaded holes drilled in so you could mount the binders where every you want. who knows why not get hyphy with a forward mount for a day and change em later.
