Replying to THALL vs. Alpha 1

I know there are already threads about this, but I wanted an opinion more custom tailored to me if you will. Im 6'2" 220 ride 50/50 park and all mtn (mostly trees and steeps) and wondered which you guys thought would be better. I already have a deep pow day ski so dont worry about that too much. Im from the east coast so trees are tightly spaced so a need a nimble ski. Durability is great and obviously i dont wanna be putting the ski into the shop after every few times out. +++++K for helpful answers thanks guys
