Looking for new park/ all mountain skis

I am a MIDWEST SKIER, for the most part. I am a park rat but do do a lot of big mountain stuff. However I have skis for the deep days. (Liberty Double Helix 182). I do end up spending anywhere from 2-4 weeks out in park city and alta every winter. I need a ski for when it isn't dumping and I want to lap the park and charge around on something no nearly as fat. I am 19 years old, weigh 140 lbs and am 5'11. I am a level III skier with a little bit of backcountry experience. I really don't want to spend anything more than 600$ on a pair of skis. I am looking for a wider park ski with a softer flex that does not have traditional camber. So far I have looked into the Line Blends, ON3P Jeronimos, Moment PB&J's, Surface One Times, Amplid Rockwells, and the Al Dentes (out of price range). I currently ride some liberty lte's. They are just too skinny and just don't like their feel unless I am hitting urban. I'm looking into any advice for other skis or which one would be my best bet.
