I have an older 16' Nez Perce that i run oar rigged. I like the diminished tubes for hauling ability. There is a noticeable difference between full tubes and diminished in the amount of gear you can fit. I don't think I carry any more than I would but my gear pile is lower, and I think that helps in windy conditions. I think it tracks and runs about the same as any other raft. You do get more water in the boat, but that just means I get to soak my kids and wife occasionally, so that's a win.
Obviously, there are some differences, but if it's a good price, I wouldn't let that dissuade you. It will be a great gear boat for sure.
