Does anyone have any experience with, or thoughts about, the Vittoria Diamante Pro clincher tire? How is it's puncture resistance (like most, it's claimed to be great)? It has a 220 TPI casing, a bead-to-bead puncture protection layer and a 210 gram weight (700x23 size). It seems like it is roughly equivalent to the Michelin Pro2 Race and the Continental's GP 4000. In contrast with these other tires, it doesn't seem to be as effectively marketed or distributed in the US. It's also hard to find any comments about the Vittoria Diamante Pro in these fora at all. Any thoughts, experience, comments or knowledges about these tires would be helpful.. Thanks.
