I have a feeling it's going to be pretty hard to find anyone on here with a significant amount of time on the Antidogma. That being said, it was a Freeskier Magazine Editors' Choice this year, which is a good sign. The AR6 is obviously a good ski as well, but it will probably be more versatile than the Amplid, should you want to take it outside of the park and tear up the rest of the mountain. The Amplid is marketed as a full-on park ski, where the AR6 is billed as a more do-it-all style ski.
