for everbody that doesnt want to read all that, the concluded that uhmwpe bases glide better when they are scraped (not grinded) compared to when they are waxed. the project deals with xc skis, but an xc ski glides just the same as downhill ski. if you get a stone grind that will mess up your base. if you scrape your base with a metal scraper, then it will glide better than if it was waxed.
