My.02 cents. I watch the riders at the snake at Mulholland in SOCAL. They get on those bikes and try to lean like some of the other guys that are near pro's and they slip and lose the bike. Now, if you stop the vid and look closely, those riders that lean way over are using racing slicks! Not this tire or that tire, racing slicks. I thought of doing that on Mulholland and hwy 178 going from the desert to lake isabella in SoCal which has some of the best twistie riding I've ever seen. But, I was going to trailer the bike with racing slicks there and back because if you ride the bike 4 hours round trip then do the twisties, you'll wear those tires out in no time. So if you really want to lean and feel 50* leans or more, do slicks.
