Re: (Another) little cutter I quite like.
Biggest issues with film sails are reefing and ironically stable shapes at least in the main. Film does not reef tradionally very well and indeed when reefed some of the built in shaping goes away. It also can't be tweaked the way cloth can to flatten the sail the way we do with gaffers or bendy masts. With head sails which get shifted when the breeze comes up its different as we don't reshape them.
Battens, especially full battens can be really nice, add much to the longevity of the sails. For racing gaffers like Sonder boats full battens came along in the 30s and indeed they may have been used back with half raters and the like, I just don't remember. The tricky bit for full battens is organizing things with the battens at the gaff, assuming they run parallel to the boom.
