I am a complete convert to the Avon Cobras on my Touring. I will never forget the first time I switched over from the Metz 880's to the Cobras. I felt like Valentino Rossi! Immediately I picked up several degrees of highly stable and controllable lean angle. The ride was seriously improved; it felt like the tires had become an active partner of the suspension; harshness decreased and stability increased - and markedly so.
As for "skittishness" in the rain; I haven't noticed this. Down here in Fla. we've been known to have some pretty significant rain pop up and my Cobras have handled this rain with aplomb. Of course, I recognize the power differential between my Touring and a standard R3, so this might not translate over very well.
I have 6K on my current set and they're not showing much, if any, wear. Should be good for at least 10K.
I run 40/40 cold.
All things considered - I think the Cobras are the absolute BEST tires you can run on the Touring.
