I replaced my 021s with a set of PR3's about a month ago. Been very happy with them in the dry, and even happier with them in the wet. Got caught in a gully washer last week with spots of at least a half inch or more of water flowing across the road. Doing almost 50 mph on the straight, I didn't even notice a difference in handling on the bike, and taking low speed turns was no concern either. Even saw about a 1 to 2 mpg increase as well! Couldn't be happier with them.
