Replying to Armada ARV 96 or Revison Tailsmen or Armada Edollo

I am 5'9.5" 145 pounds and i mostly hit rails with ocasional jumps but my local doesn't build jumps really. I am interested in the revision tailsmens but 176 cm is exactly how tall I am and the size below is 166 which would be too small right? Same With the Edollos they have too small and too big. The Arv have a 170 which is just right but i like the revisions and edollos better. I mostly ride park with some side country at my resort. This will be my second year seriously riding park but fourth year skiing. (Side note, I am going to windells winter camp so if that helps influence the descion please let me know!) Please help me pick thanks!!!
