The standard is going to vary depending on the level of competition.  As previously mentioned, at the highest level, all dubs, 2/4/+ on and off, flips off/on, probably a triple, variety of grabs etc.  Basically having all your tricks dialed with clean style and smooth landings.  At a lower level, I would say all way corks, good grabs, a dub or two probably wouldn't hurt, big variety of rail tricks and again smooth clean style and landings.  At the most basic level, rails both ways, a good cork 7 blunt, some switch spins...not really sure what you're looking for so hopefully this shed a little light.  Above all, have fun skiing!
