I don’t have any of these boats for sale.
I was making the same search as you several years ago, and it was recommended for me to try a Fusion. And I can tell you it is an excellent boat, for overnighting on float streams or doing up to class 3 whitewater, maybe even higher. It’s a very stable boat and pretty fast. Great for ferrying, and I’ve ran the Ocoee in mine with no problems, as well as the Downriver Race on the Saint Francis. I have not really paddled the other boats for comparison.
Have noticed they are pretty difficult to find a used one. Most people seem to want to keep them. I would offer to let you demo mine, if you just want to try it out. I have a Medium and a Small.
