>>4 My brother does some snowboard waxing, And here's some info:
A: If the wax is scraped up, it will drag. if you hit slush while turning at all, you will most likely fall face[back] first into said slush/snow/ice.
B: If you hit a rock or sharp piece of ice, it will most likely only scrap/cut the wax, no wax, scrap/cut on the bottom, then it wont quite wax right.
Also, i live on the eastern US, And go to a slope called "Cattaloochee" And they mainly focus on snow making.
It is the best[Really the worst] slope to learn on, five feet of ice, then slush, then ice, then powder! it's insane!
But oh so fun.
[Sorry if this is too late.]
