I camp with friends that have the Advance Elements Advance Frame kayaks. He poked a hole in the bottom of one last time we were out, he hit a decent sized submerged stick. I paddled one a while back and really liked it, it tracked a lot better than my cheapo 8' sit on top. I did wonder about the durability on our shallow rivers though. I bet that folding one wouldn't hold up to well around here as well.
