it should work. People are saying wet it...don't. It works dry. skoganskier101 and I have had a couple times skiing on pine straw. for just an in run, you should be ok. actually skiing and turning on pine straw requires a lot of it. It will work well dry. It doens't hurt your skis that much either unless you hit a rock.
Are you talking about pine straw, the long needles, or like small needles from like a christmas tree, fraiser fir, whatever?
