im pretty sure both those skiboards have 8 hole pattern bindings, foam cores, and nonreleasable plastic bindings. they suck.
ok, im gunna help you out a little.
the yellow ones are for beginner young park riders. the red ones are for people like 13 or older who just want to cruise around or stay on the bunnyhill learning. because they have a foam core and not a wood one, they do not absorb shock well. also, an 8 hole pattern plastic binding does not allow for any shiftind movement. when the middle of the ski flexes (foam core flexes way too much), because it is anchored down in so many places the binding does not flex with the ski and your boot can pop off the ski on impact. since snowblades or skiboards are so short, if they are too short for you, the impact from landing jumps with em can overtime compress your spine. if you wanna know anymore, message me. i know alot about this shit.
