Replying to Progressing into park... help me pick out some skis for next season?

Hi I'm new here and came for advice about my next pair of skis.  I just recently got into park skiing and currently ski an old pair of Salomon 1080 Foils so I could progress into the park (which when I bought them basically meant I want to be able to ski backwards and do 180s) while still having something for the rest of the mountain.

Now that I've got the basics of jibbing, throwing a 3, and skiing switch, I would like to pick up a ski that is much more park oriented: something that is a little more flexible so I'll have an easier time with butters and such.  I'd say these would be 70% to 80% park skis.  I almost never ski powder.  My price range is up to about $500.  I'm 5'6 130 lbs.
