Replying to What are you wanting in a "proggressive ski"?

With all these new shape skis such as the Armada ARG, K2 Hellbent, Lib Tech NAS with magnatraction, Line EP Pro, Moment Reno Rocker etc, with wavy sidecuts, reverse camber, rockered tips and tails there are a lot of new shapes evolving in skis these day.

What do you want in a "proggressive ski"? What kind of skis do you think would really progress skiing? Such as things like magnatraction for better hold in icy pipes, rockered skis in the park for more proggressive butters being combined into tricks etc?
