What ski should I get k2 revival, Line afterbang or Line chronic?

Basically I am in australia so our snow is all groomers or is sort of slush combined with ice when you go into what little back country we have. It is really terrible compared to the rest of the world. So which ski should I be looking to get. I want to go around the park then not have any problems riding around the rest of the mountain with my friends. The ski will also need to be durable because within one season I had almost destroyed my Public enemies.
