Big fan of Jack's cat tubes, here. I've been running Jack's cats for 25+ years, on everything from steep creeks to the Grand Canyon, and have never had a puncture. One of my early (c. 1980s) Pack Cat tubes has a very slow leak, in the end cone, which is the only quality issue I've seen. I have two Pack Cats, a Cutthroat with a Fat Pack Cat frame and my own ultralight oarframe, and a 15 ft. stretch Flyer Cat.
I also build specialised research boats for hydrology and biology work, and use Jack's tubes exclusively. They're very open to building custom tubes and discussing design changes.
This cat, for the University of Wyoming, has gray tubes to reduce reflected light for spectrographic measurements. It's basically a floating instrument platform.
