You're right, Wing is about as good as they get. Eventually one day I'll buy up that high, until then I'll stick with my Aire. Any good cataraft company will sell just the tubes to you. Usually, that's how they sell them, then you have the choice to build your own frame or buy one.

If you want to see one up close, talk with Osprey who posts on here. He builds frames and he has Wing tubes. He may show you his and that way you can get a feel for what they're like. I've heard nothing but good things about them so I doubt you'd be disappointed.

Good luck....Jerry
