Sry for dub post, didn't mean to post first one. anyway, you need the basic skills of skiing to be able to ski park at all. now rails are a different story, but if you are hitting decent size jumps like 50+, you have to ski fast, carve in and everything, etc. to be good in the park you have to be very skilled on a pair of skis and can put them exactly where you want them whether it be for grabs, to pull around a rotation, pretzeling.. you know. especially balance. and if you can carve, go fast, have good balance and great ski control, which you need to be a good park skier, you can't possibly suck at everything else.
