Laax built a big ol' end of season megabooter the other day, and Sina stomped her first ever front 10 over it. We know Kelly Clark's been putting them down in the halfpipe for a while now, but is this the first ever kicker front 10 on film from the fairer sex? It's late, we're not certain, but one thing's for sure - Sina just gave that poor big gap jump a bit of the good old Swiss slap 'n' tickle.
