Replying to Ski's/Bindings right for me?

Hi-

I'm looking to buy a pair of skis, and I really have no idea what skis would be good for me.

I'm 5'8", weigh 130 pounds, recently been skiing 40-50% park/pipe, 30% blues, 30% blacks/powder/double blacks.

I'm a good all mountain skier, a so called "type III". But, I'm not good at freestyle really (yet)- I can do 3's with different grabs/iron crosses, but would like to get better.

So, if anyone could reccommend some freestyle skis/bindings for me that would be great, thanks.

P.S. would probably be 170's and i have a budget, $600 is pretty much pushin it to the limit, if possible at all...

Thanks!
