Replying to What skis should I buy?

Alrite guys, gonna be buying new skis in a few months. I want something park specific that is flexy enough to butter and all that jazz but stable for jumps, not to bothered about getting an all round ski just something that is light. Been considering Volkl Walls, Ar6's, T-Halls, Extremes, Kung Fujas and some salomon ones like the spk and dumont amoung others. For the last few seasons i have been on some 05/06 PEs which I love riding about on but don't enjoy them in the park. I'm 5ft 6 140lbs, wondering what length is should get cos i'm gonna get them center mounted, do I get the skis slightly longer? What should I get?
