i would try using a colder wax on your edges while using whatever temp specific wax in the middle of your board. warm and all temp waxes tend to be softer then a cold wax which is a bit harder. that is also why cold waxes are harder to scrape then warmer ones. the cold wax in the edges will take more effort to dry out and wont make a difference in speed whatever the temp of the snow is since theres not much board actually touching the snow when you are on edge while carving.
