The reviewer in this article points out that expecting serious puncture resistance from performnce tires is unrealistic to say the least. However, the reviewer, a self-described heavier rider, had only one flat in 1000+ miles.
Several of the comments in this review say they've experienced punctures. However, I'm unable to find any durability comparisons with the Pro2.
Just for fun: Have you checked the tires before changing the tubes? Sometimes a thorn or a sharp piece of glass can be hard to find but still flat the same tube in the same place. A rough edge on your rim can also cause pinch flats if your tires are underinflated.
Durability and speed are not mutually exclusive properties, but there is a degree of tradeoff. If durability is important to you, I'd suggest looking into a set of touring tires. They'll slow you down a little bit, but you'll get more riding time in. (Unless you bike on some pretty bad roads indeed!)
