Hey. Likewise came across your ultralight tubes and very interested. I do a good bit of hiking and fishing in the Winds and Yellowstone, but never bring my tube because of weight. If you are still making them, how much for the tube and how much for the tube and fins. Also, how high out of the water do you sit? Please email me at qacwac@hotmail.com or call 6one5 nine7zero - 0eight3seven
