While reading through this thread, a couple of thoughts kept popping into my head, so I'll share.
I actually like thin snow conditions, though to be honest, I enjoy them more at the end of the season than in the beginning, for a few reasons.
1. I'm stronger and have my timing perfect at the end of the season
2. A benign sense of adventure
3. Joy of skiing when others have "hung them up"
Which brings me to another confession, and please let me know if anyone agrees with me on this (I have never met anyone else who admits this)
While I understand the importance of maintained bottoms and edges of skis, with the exception of boilerplate, I am drawn to runs that have something unusual or wrong with them. It could be thin cover, shrubbery, roots and dirt coming through the moguls (definitely end of season condition) crud sections, partially covered logs, gnarly rock etc. I always put adventure ahead of what might happen to my skis, I can always buy another pair or fix the ones I have. In fact, I always want another pair so this kind of makes sense if one takes finance out of the equation.
When it comes to a thin cover run (not the above one with moguls) I do the following to prevent deep gouges ..
You can usually see small rocks just under the surface. When approaching these at speed, unweight both your skis by extending both legs momentarily while passing over the area (I feel both of my ankles pulling up into the boot cuff) and you will hear the rocks rolling on your ski bottoms but will not experience "ski grab" which inflicts core damage to the bottoms.
I have also experimented with this technique in new fresh powder (early in the season) before I have my strength and timing. I have found it helpful for floatation and turn initiation and just another way to mix it up while adding to my skill set/repertoire.
