I ski on the line prophet 90s for all mountain and have a cheap pair of beginner park skis for trashing around in the park.
If you want a ski that performs well all mountain on the East Coast, the prophet 90s are the shit. They fucking rip on hard snow and grip very well even though they are a 90mm wide ski. They are stiff but not too stiff. They encourage you to ski fast and hard and really push the skis, but are not so stiff that its too much. They perform well in trees and moguls too but really shine on the groomers. That being said, I took them to alta last year for a trip and skied great in shin deep snow. In terms of park skiing they are not ideal. Not a ski to be center mounted since it would just take away from what the ski is meant for. That being said I still take em off big jumps, spin, land/ takeoff switch and are totally fine, just not as good as a real park ski. One of the best things about them is they are significantly cheaper than k2s, volkls, etc.. but ski just as well or even better.
I fucking love the p90s and highly recommend them for a ripping east coast all mountain ski. Wouldn't trade them for anything else.
