I've only looked at clinchers because we get a lot of broken glass on our club track at times. It's a place the underage drinkers like to go and hang out and they love smashing their bottles. The lack of a higher pressure tolerance on the carbon clinchers is what finally put me off them. Go Alu for the clinchers and save the carbon for the tubs. Running a set of Conti SuSos at 140psi could be the death of carbon clinchers and then you're substantially out of pocket.
