Replying to 2011 Rossignol S6? or armada arv?

First off a little bit about me.
Hello, my name is Cam and I ski in the East coast. I am an ADVANCE TYPE 3+ SKIER that skis everything. but, what I'm looking for in this future pair of skis is a ski that can handle park, groomers, powder, legitimately everything. I am 14 6'4, 250 pounds. i like a ski with a medium flex.
How would the armada arv (last years) compare with the rossignol S6 (2011) for what i want. Is there anything i forgot to mention?
