I had the feeling for a while that waxing was just a piece of info-marketing that worked really well, and noticed a difference in speed only on flats, on a slushy day.
That said, I love to wax my boards the night before a powder day...it's just a ritual of love.
Zardoz no- wax works really well too on slush...but I'm worried that it could bee too toxic. Any info on that?
On your quote, the part about saving money, you can re use scrapped off wax!
