I'm still not 100% convinced by tubs, even the tour riders are switching to clinchers for downhill sections cause of the heat/glue/rolling tire problems.
Anyway, my clinchers run happy over 10 bar (run them at 150 psi) and only weight about 180g so about 240g with a standard tube. My tubs run at 170psi and weigh about 220g each + about 60g of glue, and don't feel any different really.
