This is what the rear of a qualifier looks like after 125 track miles on a Ducati 996s. They heat up quick (1 lap) stick like glue and seem to wear evenly. I have just put a pair of pilot powers on the Busa last Friday so I'll let you know in a few hundred miles what I think the difference is. Conventional wisdom is that the Michelin's last longer.
Sorry Gunny....Both are WAY better than the BT's.
