I recently bought a Keewaydin 15 in kevlar with the carbon/kevlar trim. I've got to say, I absolutely love this boat and it's a dream at 30 lbs. I have only paddled single stick, but the kayak paddle is definitely going to get a go.
I have paddled an Osprey and found it kind of twitchy while the Kee feels very stable and smooth. The Osprey might behave better for a kneeler, but I'm a sitter. Both have quite a bit of tumblehome and the Kee heels nicely. For stability and tracking, I personally find the Keewaydin better suited. The Osprey might work better for class I-II but I haven't paddled either on anything but flat water so I can't really comment there.
FWIW, I've had my 40 lb. six year old on a harmony seat in the bow with little to no noticeable change in maneuverability.
