I bought some Lubriplate Aero this year, so tomorrow will be my first chance to see how it holds up. I wanted Lubriplate Mag-1, but I couldn't get it shipped to Canada unless I was in the market for a whole barrel of the stuff.

As for safety, I actually feel more confident in the colder weather. When the snow gets hard and crunchy, I have an easier time keeping the front wheel under control. And comfort level is just a matter of perspective. I used to work on a service rig in the Alberta countryside. If it warmed up to -20C, that was a pretty nice day.
