Yeah, the speed you ride I would think they'd do you for next season too
Great tyres indeed.
I'm on set #2, but they'll last for the rest of the season.
New tyres definately give you more grip (after 1 heat cycle).
I find the (old) tyres go a bit squirrely/greasy when they're on their way out, you can still ride fast on them, but I wouldn't push the tyre once it gave me that feedback - time for new ones!
I had a greasy front at Assen, so we changed it and it was superb - Kyle and Ian had mahoosive front slides on their older tyres!
