I like the tips & tricks thread in the touring forum, and I think one would be useful here.
Here's a few tricks that worked for me:
It hasn't been extremely cold here lately, so my hands kept getting really sweaty and I'd constantly be taking my gloves on and off which was really annoying, especially in the snow. I found that if i roll my sleeves up (leaving bare skin), it keeps my hands cooler and stops them from sweating like crazy, and is much easier to control.
I moved my panniers from the back of my bike to the front using a low rider rack, so they block a lot of the wind on my feet which helps keep them warm. So far it hasn't affected my stability enough to be a problem.
