Harb Ski Systems have some pages of easy to understand and useful looking ski tuning tips. I doubt I'll do much home tuning this season; I hot waxed the skis before the recent Megève trip but we put them in to Duvillard Sports shortly after we arrived for a proper edge tune. We'd found that Duvillard's was the best place for edges last season and we weren't disapointed this year; we even put them back in on the last day so that they're now sitting nicely ready for the Colorado trip...
