Art, I find that the PRs (and I'm running them now) don't "turn in" as easy or quickly as the Avons. For the most part, I like them. I was thinking of going with the Avons next tire switch (I had the Pirelli's before the PRs). I seem to get close to the same mileage on all brands, but I tend to change them early where you LD guys, by necessity sometimes, run them to "air" (I've seen Skooter's pictures).
I don't know how your tire wear is balanced between the front and rear tires. You might consider a Pilot Sport on the front, or ask around if anyone has tried this combo and get their opinion/advice. I know of someone who is trying that approach with the Pirelli's right now, but he's snowed in and hasn't been riding, so no report.
