I've avoided the bases and base edge angle for the most part and have focused entirely on side edges. However, recently I put a long gash along the p-tex from tip to tail in my GS skis. So I took my base flattener to it and scraped until there was no more high spot on the p-tex. But I'm thinking I should start looking into totally re-flattening the base and putting new structure - maybe the base needs a refresh now that it's been skied on for more than an entire season.
Is this activity something that's reasonable for a person to do themselves with a base flattener? What kind of structuring tool I should use?
