I'm a little confused by Swix's wax line-up (and waxes in general but that's another day ). They have a product called 'racing wax' which has a couple different temperature ranges. Here's a link to the warm one http://www.racewax.com/bio-degradable-swix-ski-snowboard-wax-ur10-6-warm/. They also have their CH series which seems to be very popular and has many temperature ranges. How do these compare? Why is the racing wax special? Just marketing or a different formulation? Thanks!
