Armada posted about mounting in this thread: http://www.newschoolers.com/ns/mobile/forumread/id/701787/.
It's about ar7s, but it's a similar issue as ar7s are recommended 2.5 back and some people mount them center. Armada staff posted:
Recommended is -2.5cm from center. As the previous posters have said, the ski is not symmetrical and mounting them at dead center will put you a bit forward of the sidecut.
However, it really comes down to personal preference and what feels best for you while skiing. For example, Hornbeck skis his at dead center; Tanner usually goes -1/-1.5cm, and still others opt for the recommended, etc.
As for binding recommendations, the majority of our team riders and employees use the Peak Series bindings from Tyrolia (either the Peak 15 or 18).
Other great options include the Salomon STH or Atomic FFG.
If we combined them and took the homosexuality of dumbledore and that massive staff of gandalf, we would have a force to be reckoned with - God
