Toko's Nordic Wax Technical Manual (PDF) is always a good read, even if you don't use Toko waxes. If you do use Toko waxes, it's a must read! Twelve pages of dense type, filled with all sorts of valuable nuggets. Examples:
- "Glide testing is more complicated than people think...The ski that glides the farthest or the fastest in a test is not necessarily the fastest ski for the race."
- "At the 2002 Olympic Games, we found something remarkable. Carbon Basewax Green, when applied EXTREMELY thick, is incredibly versatile [as a kick wax]."
- "One thing that isn't known to many skiers is that transparent bases (on racing skis usually a 6000 transparent base) are superior in at least one snow condition."
And if you use Toko waxes, there are specific recommendations for tricky and not so tricky conditions.
