the above posts describe the sub-8 and the seven-0, not the actual sub-7, which was the original design circa 2001. I bought a sub-7 w/o paddling it first (actually one flatwater paddle). I had it for 4 yrs, and used it in every type of river except a steep creek. I had a blast, it surfed beautifully, was stable, slicy enough to learn flatwater wheels, and well-balanced. I tended to grind up the edges on rocks, they became very rough and hard on the hands (gloves became almost a necessity). It took a lot of tweaking for it to be comfy. Got a little pinchy during my five days on the Selway. I sold mine last year for $350. Needed room for my beer gut
