A little about me: My name is Robert, and I'm 20 years old, living in California. I'm 6', and weigh 135 lbs (not a typo, I'm skinny), and I've been skiing for 16 years. Skiing really captured my heart when I got my Stockli Stormrider XLs- over the past 4 years, I've been going skiing just about every weekend during the season. I moved up from my (outgrown) 140's, and to something that fits me, and now I smoke all my buddies on the piste or in the trees. I know it's not all about speed, but...see below.
Why I'm looking to get some park skis: Since most of my buddies snowboard, and they're all recreational boarders (go 3-4 times/season) they like to take it slow. SLOW. And they like to spend time in the park. So, I can stick with them, or go do my own thing- which is kind of boring either way. So I thought "Hey, I can already ride switch, do my surface 360's, maybe I should invest in a pair of [cheap] twins for park use." That way I can stick with my buds, and have distinct goals to reach for, and show off a little ;)
What I need help with: I am a poor college student, and so buying skis is no small feat (I already have a helmet =p). I don't even know if I'll like skiing in the park. I thought maybe I should buy some crappy used skis so that I don't mess up my Stormriders on the rails or anything. Plus, I know for snowboards you want them detuned so they don't catch the rails or anything- and I like my skis sharp!
In short, I'm not sure what a reasonable budget is like, and what I should look for in a park ski. I know that they're all twin tips, and they come in camber/rocker/flat flavors. I don't know what manufacturers are reputable park manufacturers, or any of that stuff. So I'm completely open to any advice you have to give on picking a freestyle ski. What factors should I be looking for?
Could I get some with bindings (used) for <$150? (I'm open to ebay/craigslist/amazon/whatever)
I normally ski ~174cm- should I look for something a little shorter so that I can get it around easier?
Does the binding go in the same place as GS skis, or is it put in the center of the ski for symmetry?
Should I get light or heavy skis?
Rocker or Camber?
We've got a demo day coming up in about 3 weeks- should I try anything specific? Not that I'd be able to afford anything I'd demo...
