I liked the Pilot Roads when I tried them years ago. Better grip and handling than the Battleaxes, and hands down beats Dunflops (God, I HATE Dunlop tires!!!!) The Avon storms (and former Azarro) were superior handling tires, IMO. Life was about the same--hard to tell for sure.
Would buy the PR's again if Avons were not available in a pinch.
The concept of the PR2's kind of bother me. Sure, on the surface you would think a harder tire would extend tire life when slabbing, but I want full traction on the stoppers too. Will trade tire life for traction any day.
