Don't know yet what my next tire wil be. Currently running the PR3, and very pleased with it, but been hearing and reading really good comments about this new Pirelli, even to the point that it's better than the PR3 in the wet.
Just don't know how much better a tire can be, the PR3 has been excellent for me on the RT, enough mileage (I'm guessing I'll get to 15000kms with these tyres), and in the Alps never did anything weird or strange, even when riding in atack mode.
Don't know yet...
