Replying to Skis For Next Season

I am going to get a ski from this season for next, so they are cheap. I like to ski park a lot, but I also enjoy skiing all over the mountain with my dad. I want a ski the will perform well in any type of conditions and all over the mountain, I also plan on skiing them for a few seasons, so I need something relatively durable. I ski on the east cost and I am about 5’ 6” and 125 lbs. I am only 15 so I plan on growing a few inches before next season. Can anyone give me any suggestions on which ski and size to look at for the type of skiing I do?
