I am basically your height weight. I have been riding Line Elizabeths for a while as my park ski, but I've decided for this year I want something narrower and lighter. I demoed a bunch of skis towards the end of last season, so I guess I can fill you in a bit on some skis that come to mind:
Afterbangs - I actually thought they were tons of fun to mess about on. That said, the bases are pretty slow and they felt too soft to be reliable on bigger jumps.
Punx - Felt pretty light, fast and fairly soft. Didn't really stand out for me but they were just a good simple ski.
K2 Recoil - Fast, and turny, carved pretty well. The demo pair were a bit long, but despite that and being on the heavier side I found them easy to throw around. Medium flex. I quite liked them, but if I was buying K2 (and I might yet) I'd get the Domain which is softer. The Recoil would be the better jump ski though.
Volkl Wall - Stiffer-Medium flex. Carved brilliantly. Poppy, fun and stable. Mid-weight, great on jumps. Found them a struggle to butter on though, took a lot more effort than I'd have liked.
Unskied Recommendation:
Moment Jib - I owned the 07/08 and thought they were brilliant, but too stiff. Similar to the Walls really.
Apparently they've softened them off a ton which I think would have improved them. I haven't skied the newest models but if they are a softer flexing version of the ones I had, I reckon they would be the perfect traditional camber park ski. This is just a guess but I'd at least research them.
