New Snow Falling

The question being asked now, is what do I do with my wax? Several more centimeters of snow have fallen.
I would suggest stripping off your old wax and re-waxing. Before doing any waxing, perhaps take some fibertex to a clean base of the ski, in the tip and tail area. Do not be shy, put some elbow grease into it. It will smooth out the base, align the hairs of the ski, and if there are any slight scratches they will disappear. In colder new fallen snow you want a smooth base. In fact if it gets below -18C, I have always taken a cork and fiberlene to the base, in the glide area after using the fibertex.
You know that normally the snow temperature will be in the purple glide range area, so use that. However if you have more then one pair of skis, use one pair for colder weather. Personally I use a pair of old red Balsa-Lett racing wood skis, in cold weather (below -18C)and new falling snow. Those old wood skis should not just be for decoration, ha-ha, and taking some space.
Around #yeg, Edmonton, the trails get worn in real quick, so you are no longer skiing on new fallen snow, but the snow in the tracks become broken down very quickly.
In the kick area of the ski, take some 100 grit sand paper and roughen up that area, and then clean with wax remover.
Blue extra kick wax and purple glider seems to be a safe bet a lot of times in this area.

Have fun, GO ski!
