Replying to Armada ar5/6 or Pipe cleaner

Ok so I am deciding between the armada ar5/6 and the Pipe cleaner.
I am an expert powder and groomer skier, but I ski park a lot more than anything else. I am an Intermediate on jumps. A beginner on rails. I haven't done much pipe yet, but I plan to get into it.
I want a ski that has good pop but will not fail me on rails and boxes.
WHICH ONE SHOULD I GET???
btw they would be center mounted and in between a 170 and 176.
