I too have been very pleasantly surprised by the Dunlop Bluresponse , they have great grip and that is comparing to Yokohama AO48 barely legal street/track tyres.
Ok the AO48 are in a slightly different league in the dry, but they only last (on my Elise) 8000 km on the rear axle and they are as loud as hell. And they are hardly usable in the wet. But I agree with you, the Dunlop Bluresponse are a positive surprise.
