@AJT660 When you say front end patter do you mean the wobbles at high speed? That's what I get when going over 80 mph. I have to loosen my grip on the handlebars or the wobbles get dangerous. I didn't get this wobble problem with the original Pirelli Dragons but they wore out too quickly. I do like the grip the Distanzias give and can say I've had a few slips with Pirelli tyres but the Avons stick really well.

I'm getting another Distanzia fitted to the rear this week just because I like to keep matching tyres but when that's dusted I'll be trying some Continentals as I've heard good reports on them.

I give Pirelli Dragons 6/10. (wear too fast and lack grip. Rear squares off too quick).
Avon Distanzias 8/10 (Last 50% longer but getting the wobbles).
