Alex, I have a few types you can borrow if you want to try some if this bloomin' wind ever dies down! I have a Fat Cat, a U and a donut so it will give you a good sampling.
Just curious though, are you planning on doing some hike-ins and want something lighter than the WM? For me, that is about the only time I would pick a tube over a WM or pontoon and as you know, if I can wheel in, I still don't take a tube if I don't have to, lol!
