I am pretty stoked about the Mich PR2's. Good wet weather performance and dry traction...but what is impressive to me is how well they resist squaring off when i run them at 36F/42R pressures. They maintain their profile very well. On the FZ1 got 10k out of the front and should get 8k out of the rear in mixed riding.
Wouldn't mind trying a set of PR3's though...for comparative purposes.
