Well, I can, but I don't have your snow.
I check the structure (thin linear - the snow here is mostly dry and cold, especially in December and January). If there are areas that seem to be fading, I use my SkiVisions structure tool
to refresh it. I then use a flattening tool to knock off the high peaks of the fresh structure. (It makes them more like a plateau than a Teton.). I brush a lot to get the bits out of the valleys.
Then I start waxing.
Basically, I do hot wax and scrape repeatedly until the wax I'm scraping is clean, using any brand of warm wax, just hydrocarbon. Then they sit overnight unscraped. (This is pre season). Then I wax with CH4, do a light warm scrape, let them sit. Warm scrape again, then thorough scrape and light brushing. Set aside until season. Apply CH2 powder to about half inch along the edges, then "wax for the week" (which in Montana will probably be green).
Because I start out with green for probably the first six weeks or so, there's going to be a pretty protective wax on the skis most of the winter. Sometime in mid to late February I might be using red. I rewax about every 60,000 vertical feet, roughly, depending on my ski schedule. I like to leave it sit overnight so I'm not brushing and scraping in a rush and doing a half assed job. I use a plastic scraper and both hand and rotobrushes to thoroughly finish the skis. I feel brushing out the structure is most important in certain kinds of spring conditions and super frigid winter conditions. Maybe sometimes you can skip it, especially back east on man made, but since it's going to be several days, between using different skis and depending on usage, I don't want to assume I don't need to and then find out otherwise. I ski five days a week, and pay for a locker so I'm not dragging skis home every night.
I also, now you're really going to hear how nuts I am, keep track of what wax I used, what steps of tuning I performed, on each set of skis, so I can look back in time. I'm getting old now, I need to remember what color wax I put on which pair of skis so I can decide if the next "tuning session" needs to be for a set I did two weeks ago when it was warm and I haven't really been on them much, but they really need different wax so should be brought home anyway.
I also work on the edges every time because I'm dragging home the skis anyway, but didn't cover all that.
I don't think what I do is much different than A-man or Jacques.
I occasionally will use Racewax Universal fluorocarbon in the spring if I need to because the snow is wet. But for here for December through February, it's just the regular hydrocarbon. I've used some other waxes occasionally, but haven't liked them as much. They are hanging around unused unless for some reason we've got conditions that are unusual for us. Then I'll start experimenting. Usually that's late in the year. Last year after a lot of experimenting, with mixed results, I just did a mid season "pre season" prep and things were working again. (We had a really warm winter and there was pretty much every type of snow on the mountain all at once and I was moving around trying to stay on the drier snow without regard to terrain or where my friend wanted to ski. Instead of matching my wax to conditions, I was trying to match conditions to the wax! But we've got 360° degrees of skiing, with wind blown, treed, some man-made, you know, everything, so with the crazy weather -- foggier and warmer -- knowing the night before was tough. I found the fluorocarbon helpful. But also having another pair in the locker was helpful.)
