the ar5's are light. I'm on a pair of t-halls right now and they are okay for all mountain but the ar5's are stiffer, and better carving. The pop on the t-halls is sick, and they are really light. I ski public enemies for all mountain though, because the tanners are not the best on an icy day outside of the park. ANd the rounded edges were cool, They don't affect carving at all, but made rails a lot smoother on the first day.
