Just to let you guys know...
ROCKERED DOES NOT EQUAL REVERSE CAMBER...
Reverse camber is when the entire ski is completely reverse.. such as the spatula or pontoon. there is no flat spot in the middle, or if there is, its quite small, and there is no natural camber whatsoever.
the EP Pros, ARG's, Hellbents, Moment Melees, etc all are rockered.. (or in Line's language, early risen) If you are to stand on any of these skis, you will either notice that the bottom is flat, or, that there is a little bit of natural camber (the Hellbents and EP Pros especially show this off)
the natural camber allows the ski to at least work SOMEWHAT on groomers.
The Hellbent for example.. works on K2's 3 piece rocker system. Where the tip and tail are practically whole different parts of the ski, than the natural camber middle.. so it creates sort of a wavy lookin ski.
the EP Pro, has a natural camber, but the tips rise up and taper in.. sort of the opposite but equal effect.
I'm not 100% sure about the ARG, but it's probably a similar effect if you notice the crazy sidecut dimensions it has...
