I've had better luck with the Challenge PR tubs than the previous poster.

All of mine have come from Ribble or Velomine, if that makes any difference.

Smooth as silk.

I've also had good luck with Challenge Criteriums for that matter.

FMBs or Dugast?

Sure, why not. I just don't feel like like spending that kind of $$$ atm.

Rootboy, I like the new Veloflex logos. I think they look fine and the tires are outstanding.
