How much was gained afterwards? And was there a noticeable difference in pulling power?

In the summer I was getting just shy of 5.5 but now I think I'm around the 4.5 range.

I still have a couple things to do yet which could bring these numbers up. One of which will be to change my rubber. I had a big lug continental tire in summer and switched to bandag bdr-w winter grips which have a horrible rolling resistance.
