Got a pair of hutchinson fusion 3s and installed them on vuelta rims with duct tape. A pain in the ass to install. I generally can install and remove tires without tools no problem. with the fusions, I broke all my plastic levers. I had to work at it for several days until I mastered the technique. Once you get the technique, it is not as difficult. The front wheel got sealed right away. The rear gave me trouble at the valve. I had to disassemble and start again. The trick is to seat the valve really well. I accomplished this by making a small hole in the valve hole and push the valve down while I tightened the nut. Once you install the stuff, it pumps easily with a floor pump. If you get everything installed properly, and you do the shaky, shaky, they will seal perfectly well. I rode twice without problems with 95 psi, running over humps, potholes and rough roads. I haven't checked the wheels for a week and they are at 80psi today. If they hold I will stick to them.
