There is often a tradeoff between getting the lightest bike tire with lowest rolling resistance, and punture protection. Sometimes it gets even more confusing when other variables are thrown into the picture, so you're often left with the question "Whats really going to be good for me?" What do you do, pay more and get sketchy tires or pay less but get weighty but durable ones?
Germany's Tour magazine had published the results of rolling resistance tests for clinchers to go along with their previously published testing of tubulars. All the tests were performed at the Continental Tire facility.
