My Dunlop GP tire received a stern beating last Sunday on an all day ride. It performed great. I did feel it sliding a bit under extreme cornering but it's not like I can say it was the tires doing since the road surfaces were so inconsistent. The wear on this tire is far beyond optimal as well. Great tires and I'm just out there using them up. I wouldn't mind running another set... hell the street version Qualifier was a fantastic tire also. I don't have a preference between the two as I'm out on the street and they both are performers. I also make damn sure that any tire I have on is warmed for a few minutes in the turns before I use em hard. When people slip up it's almost always on cold tires it seems lately.
