Replying to ON3P kartels 171

Ive loved the look of ON3P but I've never skied them before. About to buy some Kartels off a guy tommorow. I'm about 5'9-5'10 and about 140 pounds and around the intermediate level. I ski park about 95% of the time caz the mountain I ski at is basically a "hill". I haven't done a lot of research on them so I'm wondering what you guys think about them. I've heard good things about them but I'm looking for someone who has skied them before.
