Replying to Armada choice.

Recently, with saved money and christmas money... I got enough $$$ to afford some new skis. As my park skis dun-broked ive had only powder skis only for a while and really want something thats more stable with more of a stiff center and tail.

I demoed
-Icelantic Denalis
-Armada Alpha ones
-Armada T-halls
-K2 Domains
-Volkl Walls

I narrowed it down to either the alpha ones or T-halls. I love both skis, but what will be my long term benefits or losses to each ski? (looking for answers from people who have owned either). Thanks, +++K for good answers.
