Replying to Playful pow ski?

I'm looking for a rockered powder ski that I can still use all over the mountain when there isnt much snow. I'm 6" and 150lb, and i dont want a very stiff ski but it still has to be able to hold an edge. I was thinking Armada JJ's 175, SirFrancisBacons 172, or K2 obSETHed 179. I've heard different things about all of them and was wondering if anyone had tried them and what they thought. Other suggestions would be great too, thanks
