I agree about light tubes being a total disaster, and a joke, and a big fat waste of time.

I had a shocking run of flats with Continental Race 28s (~53g) and the light Tiogas (about 70g).
Most of the flats I was getting weren't even punctures, but the tubes were tearing tiny little holes. They'd get scuff marks, near the middle of which were the teeny, pinhole tears. No joke, at one stage I was getting 3 flats a week, which is when I obviously got fed up with them.
