So I got a cheap pair of former-rental XC skis this fall and am having trouble on slick hardpacked hills. The scales on these skis are quite shallow compared to my old pair, and I think that's preventing me from getting good grip.
Has anyone re-cut the scales on their skis to deepen them? Any tips to pass along? I really need a good base grip on these skis as I do most of by XC skiing pulling a loaded Chariot.
