From your info, I would say ARG. I got to ride a pair last year, and I shit myself they are so fun. They are a fairly stiff ski so you can charge crud like no other and the float is sick. Because of the tip and tail taper and the rocker, you can ski in the front of your boots while skiing pow and not tip dive. You can control how deep you want to go into the snow by leaning forward or leaning back, but you will never tip dive. Also, the ski is surprisingly light and the swing-weight is almost nothing. Probably the most fun ski I have ever ridden, and if your primary focus is pow, I highly recommend them. They aren't the best in hardpack, but once you get used to them they are certainly manageable and get you from one place to the other with out a problem. I feel like the ARG's will be a big step up from the Bent in terms of being able to charge crud harder, stomp airs better, and just all around ski everything harder and faster.
