I was lucky enough to compete in skier-x many years ago at winter-x. The quals where all done through the lord of the boards series (an old uncle-E joint) and espn-sponsored one mountain events held across the country.
The first few years where mostly cross over big-mountain and freestylers - but once the money got large then all the huge x-racers from europe came over and killed it. Standing next to a 230-lb swede and some HGH'd x-us b-teamer with nothing to lose was fucking scary and sketch ball.
The biggest problem was that we ran a snowboarder course and the jumps were WAY too small. Everyone overshot every feature, going three strong over a jump taking it to the flats at 50mph was dangerous.
I got out of it in 2000 when I realized I sucked compared to the nut jobs with wax pros and 50lbs more muscle than me.
There are still local quals every year - I know sugar bowl has an x-games qualifier every season - good luck against Rahlves and the Hudson brothers there -
