You call that cold? -29F (-34C)? You have strange standards for whar qualifies as "cold". Around here, we call that OHMYFREAKINGGODTHISISANTARCTICAANDWEWILLALLSURELYDIE!
Last night we set two records: before midnight, a new record low for Jan 5 of -35F (old record was -19F in 1971), and after midnight a new record low of -38F (old record was -26F in 1979.) A very chilly evening, to be sure!
Perhaps if you don't have the undergarments thick enough and wind blockie enough to ski in these temps, then this might be a good use of the Swix wax you have lying around but don't use. Iron, scrape, brush per instructions. But don't smoke the stuff -- those fluorocarbons are unhealthy.
(I've never experienced such low temps even in my Rochester and Chicago days. Must be interesting -- once.)
I checked last night, and also early this morning, and missed those lowest points, at least as reported on Attackpoint. Brrr indeed!
Fluorocarbon wax? Pshaw. Swampfox uses nothing but bear grease on his skis.
Iamstillhungry, I have borrowed freely from the Texas philosophy of counting, best personified by your ex-gov Rick Perry: never use numbers 3 or higher when 2 will do. To the end, I have limited my wax box to two: warm glide, and kinda cold glide. For anything colder than kinda cold, you either say "screw it, my arms are strong" or else you say "screw it, I'm gonna run instead." Of course, you could search further afield for other philosophy in that situation, which would lead you to the Trumpian school of thought: "just screw it, whatever it is."
Texans have a different decision making tree. It's either, "God said wax," or "God said don't wax." Then you shoot the ski and drink a beer.
-38F? Cool off a bit and you can reach that point of happy convergence where Celsius folks and Fahrenheit folks can finally agree to get along.
