Yo, yer' both correct in different ways, as a longtime whistler skier i can say that there are many locals who rip like hell, many of them become guides, patrollers, forest fighters and the like ilk, and can hold their own against the likes of Morrisson in the BC. Hell they're the ones often spotting the routes for all the "name" skiers.. it's more or less a choice of profession in the end, and yes, all those guys are mad humble, those who aren't (usually the Quebecois, heh) get their asses handed to them by mothafuckin nature. But at the same time ripping up a local mountain even like Whistler, Jackson etc is no excuse for true big mountain experience.. in this the Canucks from BC have a distinct advantage as if you rip Whistler you rip the backcountry and the interior, and that's where you learn...
Anyway I've been remarkably impressed by Mark Abma but the entire sport is so accelerated that it's not 'who will be the next Seth Morrison' but 'holy shit, there's a fuckin' swarm out there'..
On the other hand I've never seen anyone ski technical style like Scot Schmidt and many of the Europeans who can do tight ice chutes at 70 degrees like nobody's business. And then' theres the ski mountaineers who have their own scene with the climbing community and they are on an entirely other level here -- I guess this is the level Seth is getting into with his BASE jumping.
