here is my opininion on the ar5:
I have the 03-04s, and I have ridden them for a season and a half which is about 45 days on probably 40% park 60% all mountain. I find these skis to be quite lightweight- they are just a bit heavier than the old lines (I don't know how heavy the new ones are, I had the orange skogans) which is really light. However, they are still very sturdy for all mountain riding with their super stiff tails. Durability wise, they aren't great, but they aren't that bad either. Right now the tops are covered in chips, however this doesn't affect the ride. The bases seem a bit thin and I have collected many core shots. The edges are all cracked up under the bindings and are starting to curl up at some of the cracks, but they have seen a lot of rails, so I don't really know. I am hoping to get one more season out of them but I kind of don't think they'll make it. Anyways, these skis are really fun to ride and really light, but not the greatest as far as being able to stop bullets.
