Replying to Park skis? Walls, Chronics, ar7, sixth sense, addicts?

I'm in the market for a new park ski.  I used to ski 177 4frnt stls and liked them, however they are beat and I need some new skis.  I am 5' 11'' 155 pounds.  Other than skiing park on these skis I'll rip some bumps and groomers, which makes me think camber would be a good idea.  I guss you could consider me a medium size park feature skier, I don't have any experience on breck freeway type stuff.  Looking for a ski in the 177-182 range.  I have considered Volkl walls, Line chronics, armada ar7, fisher addicts, and dynastar sixth sense spins.  Any advice?
