+1 for Pilot Roads. I replaced the rear PR2 on my F800ST with a PR3 at 8.5k because I was about to go on a cross-country trip. At 11.5k now the front PR2 still looks like it has a few thousand miles left, but I'm swapping it for a PR3 just to be safe on the 4.5k trip back. Handling in all weather is confidence inspiring, even with 10+k on the front. I can't really tell the difference between the PR2 and PR3 when I'm on the bike.
