Replying to Need help choosin skis

I'm looking for a pair of new skis for the upcoming season. A little about me: live on the east coast, ski sunday river every weekend. I'm 16, 5'8 and 150 pounds. I skis 70% park and 30% all mountain and trees. In the park, I'm mostly hitting rails. I'm looking for a light, DURABLE ski that is mid-soft flex. Some skis I was thinking of: soul riders, da Nollies, halo 2s, fatypus l toros and filthy riches. I'm mostly interested in the filthy riches and how they will float on the occasional powder and some trips I will be taking this winter.
