Skis for me

I'm sure you're tired of seeing these threads, but I really need some help.

I've been skiing since I've been 3, I am now 15. so I would put myself in the upper intermediate class, I guess? I've never really been interested in to the park aspect of skiing until the past to or so years. I'm currently on a pair of K2 Omni 2.5's (link= http://sportsbay.com/omni25ibc100.html[bindings too]) they've been a good ski for the rest of the mountain, but not so much in the park. I am from the oh so wonderful icy east, my local mountain is Shawnee peak (http://www.shawneepeak.com/)I still want to very much be able to hit up the rest of the mountain with out having to muscle the shit out of my skis for that to go well.

so, 40% park 55% groomed 5% pow.

5'10"-11"
140
high intermediate
Icy east coast.

Price limit $500, I don't need bindings.

I hope thats enough, ask if you need more info.
