Anyone have any experience with the perception overflow x (kayak)? I just stumbled onto a great deal and was looking for a white water boat. I am about 155lbs. The water i'll be on will be smaller rivers, id say class 3 and 4. looking for any type of advice on this thing. I've done some really lame white water stuff in the boat that i use to fish out of, a perception swifty 9.5. Does anyone know how the two compare?
