ar6s are fairly stiff/solid especially because they are geared towards all mountain, like the line blend. When compared to the anthems, ar6s are stiff. Durability wise, most will say ar6s will last you longer, but i dont have long term experience with them so i couldnt say. however, anthems are the best rail ski in the world in my opinion because of the fatty base and edge; its not just a marketing ploy. My edges and bases are still is great condition after one season. the topsheet complaints are true unfortunatley, they are pretty soft and i have some big chunks out of mine. But when it comes down to price and what i want in a ski, anthems are the obvious winner for me...
