Wortmann vs Eppler
Not all 70’s gliders are that bad, Put laser cut templates on my 1980 DG200 with original gelcoat, and it was close to perfect. The PIK is known to be terrible in this aspect, one that I know of is 19% thick rather than 17%. Back in the day a couple of guys I know reprofiled a Mossie and a Mini, with very good results.
