Replying to Armada AR6 vs Volkl Wall. Help!

I'm trying to decide which ski to buy.  I ski about 60% of my time in the park, but prefer a stiff ski as i'm 6'1" 200 lbs. I ride my skis hard and hit jumps more than than rails. I want the best overall ski of the two, the one that will perform the best outside of the park, and the one that will last the longest. I can get the Wall for about 70 bucks cheaper.
I'm pretty sure either ski would be good for me. I currently ride the '05 AR5s and love them.
If anyone has ridden both skis could you give me an idea of which ski I should choose? Thanks.
