so i'm pretty small. i really don't think you will have an issue. these things carve better than my fujatives and my punx. i've got a racing background so i love laying into a hard carve and not having to worry about losing an edge. they carve off lips well too. the sidecut is predictable and smooth. they don't hook switch and are surprisingly forgiving. we don't have any jumps up in the park at my mtn yet but i've already thrown a few backflips, fronts, three's, switch threes, and butter threes. i was getting three's and switch threes off a roller with a bump on top for a lip. probably going about ten feet out. so they really spin pretty well. i was surprised at how much i like these skis. i'm sure i'll have no problems with 7's over 40 foot kickers on these skis. they really spin well. i need to ride them more in park, but i'm considering getting rid of my park skis. at your size, i really don't think you will have a problem with them. but they will be bigger than your skis so they'll take some getting used to. but i love them for jibs and stuff like that. they are super fun on rails too cuz they are so wide and stable. i do struggle with 270's onto rails with them but i really suck at rails lol. but they are super stable and with some practice i really think they'll be a lot of fun in the park and i know they are epic all over the mountain.
