jackvanlieropIm 5'8'' and 115 pounds. price range would be under $600, for 90% park. In the park a lot of rails and jibbing but for sure medium sized jumps like 40' kickers but not huge jumps for dubs or anything. also a little urban and powder skiing but not much. A symmetrical ski doesn't matter very much for me. I really like to press, butter, surface swap, and 50-50 so something 85mm in the waist or wider preferably.
Ok, so some skis that will fit well for you:
J-Skis 90mm platform - Who knows what they're going to be named next (currently it's The Straya). Soft, durable, fun ski. Rockered tip and tail will prevent catching and help with butters and presses.
J-Skis 98mm platform - Basically the same as the 90mm platform (currently the Twister), just 8mms wider.
Line Traveling Circus - New version of the old Anthem (plus rocker), cap construction will be a bit more annoying while carving, but they're symmetrical and soft. 93mm underfoot.
Line Blend - At 100mm underfoot, they kinda max out your waist width, but people ride them in the park all the time. Wide platform gives you more room for surfaces, and the soft tip and tail with rocker will make butters no problem. These will have the most float of almost all the skis though.
Rossignol Slat - On the stiffer side, but still a lot of fun. Race base keeps them fast, camber underfoot keeps you in control, the rocker tip and tail lets you butter (you might have to work for it a bit more than with the other skis, but it's possible). 98 underfoot.
Armada Al Dente - The name itself means "noodle" basically, and it's that. Rocker only in the tip (which I find weird in a park ski, but whatever) on top of the softness of the ski will let you butter whatever you want and the 98mm waist will help with surfaces.
Nordica Soul Rider - The things you like to do sound a lot like Keiran McViegh, so why not get the ski that he does them on. You'll be able to do all the butters and presses you want on these skis, and be in control of them while you do it because of their flex. 97mm underfoot.
ON3P Filthy Rich - I love these skis, easily my favorite ski on the list. 89 underfoot, but a ton of rocker lets them float in up to 6 inches of powder. Super thick base and edges keeps them going for a long time. Bamboo core makes them fun for as long as they live (in fact, they tend to get even more fun the more you ride them). Super snappy and responsive. Quick edge to edge, and can carve like a dream. There's no problem with butters, presses, surface swaps. But they're also super stable at speeds and on larger jumps. At the very top of your price range, but worth every penny.
ON3P Kartel 98 - The softest ski they've got in their line up. Awesome for butters, presses, ect. 98mm underfoot, so a bit on the wider side, but definitely designed for park use. Bamboo core keeps them lively and snappy for a long time. They'll hold it down for big jumps no problem, so medium jumps are a sure thing. Super thick edges and bases make them some of the most durable skis on the market. The rocker in the tip and tail will make butters and presses even more fun and easy, while giving you some float in the powder. This is honestly my top pick for what you're looking for, however it's just slightly above your price range at $649, but if you can swing it, you'll love them.
I recommend doing your own research on those particular skis, and see what fits you best.
