John,
I really like this style of float tube better than my old Woodriver Stealthrider. You really notice the ease of kicking compared to a tube where you're more fully in the water. It does not compress down like my old one did, but the material is thicker on the bottom of the tubes and the seat bottom and back has foam in them for comfort. For the price, it would be hard to beat. We just did an update of the more popular float tube models in our float tube section located here

We listed models from Bucks Bags, Caddis, Creek Company, Outcast, Trout Unlimited and Waterskeeter. I think Woodriver is out of business or something, and Trout Traps I cannot contact anyone to ask, so I dropped both companies products because I'm not sure about the availability of their products. All I know is I'm looking forward to using mine alot more this year and in the "Big Salty" in particular. Talk to you soon,
Perry
