Replying to Which one: armada ar6, thall, line invader, or something else?

im like 5'6 so im probably looking at a 166-170. i want a ski that will handle really well in the park cuz thats what i mainly do but will also be able to go all mountain. the ar6 seems good all mountain, but i really want something good for the park that is light. but the line invader and thall seem like park only skis, how would they do all mountain?> or what other ski should i look at?
