Is it just my cynical imagination or are most of the companies making rockered skis now trying to modify them to ski more like conventional skis because a fully rockered ski doesn't really work for area skiing? The leading edge is definitely beyond rocker and into the "hybrid" area as Spindrift has noted. It'll be interesting to see if things like Armada's "elf shoe technology" actually produce a ski that is practical in more than very limited snow conditions.
I've got a conventional "powder ski" (Watea 101) with minimal sidecut, turned up tail, and virtually zero camber that works fantasitc in powder and reasonably well in all other conditions. It seems to me that if I go to a serious rocker I'll gain powder and bad snow performance at the expense of everything else. I agree with Beyond's analysis. If you give me a well constructed ski with the right flex pattern I can usually make it do what I want in any snow condtion or terrain, regardless of sidecut, so IMO the magic properties of rocker mainly come into play in pretty limited circumstances (bad snow conditions, very tight trees, or endless bottomless powder).
There is no question a fat rockered ski like the Pontoons can allow you to ski really bad snow conditions reasonably well that are virtually unskiable on convential skis, but that's usually the last place I want to be most of the time. It seems to me that rockered skis are a specialty tool that they are now trying to make less special because they are currently not practical for 95% of skiers. Until they get it figured out, I'm still looking for a conventional type ski with a little tip rocker to increase funky snow performace rather than a de-rockered (multiple sidecut) ski trying to increase hard snow performance, but who knows, maybe elf shoes really are the future.
