I wanted to try these latex tubes that are advertised to have slightly better puncture resistance than other, lighter latex tubes. I also moved from Michelin Pro3 Race tires to Continental 4000s for the same reason. You still have to be super careful putting these tubes on. Don't even think about using a tire lever. Given how fragile they are, the fact that you have to put air in them every time you ride, plus the fact that I'm still not convinced they give weight and rolling resistance benefits you can feel, I'm not sure they are worth the cost and effort. Maybe if you are Pro Tour level it is worth it, but doubtful for the rest of us.
