I paddled one for 10 years, and I am at the high end of their capacity. I bought it weighing 240 lbs and went up to 320 lbs. (I'm lighter now, lol) When you fill one, they bail kinda funny, like a submerged ball. They aren't stable until the cockpit is only half full. Hard/ pushy eddy lines tended to flip me as much as rapids, I had little trouble with big waves and holes. Higher volume stuff was pretty fun, I really like the low volume pointy nose for big waves. You didn't have to climb to the top of a wave, you could punch through pretty easily, and the wave isn't trying to kick you sideways if you hit them head on. Boats like th e Lynx tended to do that to me. I didn't like it for small rock ridden rivers, it has a hell of a long water line for creeky type stuff with no rocker. I seemed to always get hung up on little piddly rocks, and some would flip me. I once went off a 12 foot waterfall no problem, and proceeded to get caught and flipped on some tiny little low volume class II just below it. Hope this helps.
