When several patrol are in the shack at the top of a run, their skis are laying in the snow in front of the hut, 3 or 4 pairs, and you can see what they're on. Mostly good, current stuff for the full-time pros.
One thing I thought about when seeing their skis on a day that was early season, sketch coverage, icy: That they have to beat up some good skis on rocks sometimes. They have to be able to hold an edge on a steep pitch even if rocks are everywhere and they know their skis will take some hits. Also, they don't have the privilege of skiing where ever they please to avoid ice; they have to go where the injured skier is. So they bring out good skis on rocky days.
Also, I often see patrol intentionally skiing the worst snow on the mountain, actually going out and finding it, horrible frozen set up tracked snow, just for drill, for that occasion when a skier gets into trouble in some god-forsaken spot on the mountain. That takes some type of charging, crud busting, powerful ski (Legend Pro has some popularity for this reason.)
A pleasure skier can just forfeit that edge hold for a few days, riding rock skis until there is coverage enough for the pristine edges to come out again. Patrol can not.
