Magley and I both have PDS and neither of us will change anytime soon. We both ride quite hard and have no issues. NinjaNick and xtremef4i both have Roadsmarts, I think, and run hard all the time and love them. My father runs PR2's, rails them and is extremely satisfied. IMO, there's not reason to buy a supersport tire, the sport touring tires are going to give you all the grip for hard riding on the street plus the bonus of extended mileage for a lesser price.
