Jon:

I found the Hakka C' to be a little stiff as well.   Last summer we were unable to get our hands on a set of Hakka C's before we left Calgary to head east in the Hyena, so we went with XL rates Nokian eNTYREs (which are rated at 99 or 100) ... I had to work through the math a couple of times to prove to myself they would be safe and adequate.   I checked them every morning and evening over our 5500km trip home.  I've since rotated them and put on another 4000km and all is well.
