Yup, just put a PR2 on the front 2 weeks ago (replaced a PR1). So now I have PR2's on front and back and they seem great. They are very predictable and well planted on the road.
I did a week long trip last week in New England and one day it poured rain for the entire day. We were in New Hamspire and the tires performed very well. As the day wore on my confidence in the tires grew and I became very comfortable with them, even in such a heavy rain.
The PR3's worry me a bit with some of the recent reports of problems, so I'm glad I selected PR2's when it was time for a replacement.
