Vail has the best pipe in all of Colorado hands down.  Breck, Copper, and Buttermilk's don't compare.  Sure Breck hosts Dew tour, Copper hosts the Grand Prix and Buttermilk hosts X-games but if any ONE of those comps were to move to Vail I guarantee it wouldn't ever leave.  I rarely have anyone in the pipe the same time as me at Vail too, unlike Freeway when people will drop in halfway down sometimes...
