By the time my Vittoria Rallys get 1800 miles on them they are ready for the trash anyway. Once in a great while I will flat a good one. To be honest, I don't notice a huge difference between the Corsas and the Rallys, only about $ 75.00. They have been extremely reliable and comfortable to ride. I do agree on the safety issue about flatting on a clincher at speed vs. a tubular. It is scary to see someone go down when their rim hits the road. That said, if I ever get a new bike I might go the clincher route...
