Swix CH6 Blue 21 to 10 deg F
Toko Red S3 Hydrocarbon 25 to 14 deg F .Economical
Swix F4 Fluoro for wet snow, also ok for an all temp wax.More expensive,gives off nasty chemical fumes if overheated
Swix CH4 for below 14 deg F down to as cold as you may be out there. Must be scraped when warm otherwise just chips off and flies everywhere.A real pain to work with.
Last winter I used CH6 for everything until wet spring conditions then Swix CH8.
Obviously , these temperature ranges are just guidelines.
Heads up, I used Holmenkol Orange(23 degF and up) for a storage wax, as it was inexpensive.It stained the bottom of my lighter colored bases.I can't recommend it for anything except black bases.
You can't idiot proof anything because fools are so damn clever.
