Do not get the T-hall as an all montain ski, Its terrible in powder and does not carve to well. Its great in the park but no fun out of it. Simply the flex is far to soft, on hardpack the ski just bends in half when carved hard. In powder its just not much fun at all. I would look at the AR7 or ARV if you want an armada all mountain ski.
Other skis that are good for what you want are the salomon 2012, the K2 kung fugas or as said before line blend can be good. Even my suspects are better all mountain skis then my T-halls but not as good as the others I mentioned.
