Well, the temp was up near 70oF this PM, so was able to put a couple of hundred miles on the new PowerPures.
I initially did feel the hesitation Cortez described above a little bit...mostly when the tires were cold (AM was cool...about 40oF), but VERY little and really not an issue at all.
As they warmed up, I no longer felt anything resembling hesitation or slip. What I felt, instead, was lots of very good traction and excellent cornering on the twisties. Very confidence instilling and exponentially better tires than the Bridgestones they replaced.
I will buy these again! Very impressed...thanks for the recommendation, Cortez and others!!
Here are a few photos from today, taken on the west side of the Sutter Buttes...the smallest mountain range in the world!
