Conti SS tubes also aren't too reliable. Have used for many hours on an indoor velodrome no probs (which in hindsight was a bad idea) but managed to flat on the 3 mile ride between Chorley train station and some hill climb I rode last year, in the dry, in July (with Conti SS tyres, that are pretty good at resisting flats).
