I had terrible luck with the Corsa G+ 1.0, flatted after 250 miles and when I inspected the tread there were small holes and thin sections letting light pass through everywhere, which did not give me confidence to run them any longer. Shame because the skinwall looks fantastic.
No such issues with Conti GP 4/5K TL, Michelin Pro 4 Endurance, or Schwalbe Pro Ones TLE. Only other tires I've ever run that were close to as weak were the Specialized Turbo Pros that came on one bike.
