some mountains, like mine, are mostly rock. skis take a beating early season until the coverage is good.
so your best skis don't go out for a while and you need to ski on something. enter the rock ski.
around here there are several solutions:
classic top end skis with lots of good days on them, your go to ski in their day, now dull and full of core shots, like the Volkl G-31
similar, a beat up ski only a few seasons old, that had been your daily driver until you beat the edges up and ruined the bases.
different, I once bought some skis that were not great but cheap as a Rock Ski. didn't work 'cause a rock ski has to do everything well, except hold an edge.
