Your spending lots of money pretty often for tires out of 95% of riders needs. Look at the metzeler z6 I have a 1000cc twin(torque monster) and I can't get the z6 to slip, used to have the Metzeler "race" tires and I like these better.
As for the scrubbing, I spray some more of the soap I used to mount the tire with, rub it with a rag, and rinse off.
