I have.
It is an outstanding tire, marred by one very unfortunate trait: the rear treadlife is abysmal. Many can't even manage 3000-4000 miles before they are toast.
However, while it does lasts... these tires are pretty amazing, particularly in the tighter twisties. They offer blazingly fast transitions, and you can really lean that bike over to a degree you probably haven't before, all with extreme confidence.
But the damn things just won't last, is the only problem. Otherwise, I'd liken them to the Avons in performance (except in wet weather, where the Avons really shine.)
