i've done it by mistake before, but i've seen video of someone doing it on purpose and then spinning off after, i don't remember what vid it was though
i'd actually say my best jib is a switch 5050-sw360 out. we have this big 25 foot up box in our park which i hit switch with plenty of speed and float a nice sw 3 off, i think its super fun.
like onto a box? i remember seeing a video of charles gagnier and he crosses his skis and goes onto a box and then uncross's them when he gets off, MADD STEEZ
"I would quite masturbating to be able to ski again, i sware!"
