You could always get the boat made in the whitewater layup. I came very close to buying that boat a few years ago. I test paddled the Otegan and a strip built Blackwater that was used to make the mold. The Blackwater was quite stable and had good speed. The only reason I didn't buy it was that I was able to get a better deal on a Rapidfire which included a paddle. I still would like to get a Blackwater though. As for durability, I don't think you could go wrong with his lighter layup either. I looked at many of the boats John uses and stores at his shop. They all look to be up to the task of handling some abuse.
I would think IMHO a carbon outer with an extra layer of kevlar in the bottom of the standard layup would be a tougher boat than a ultralight layup Wenonah.
