Come to think, I have to agree on ductile 3003. Just doesn't look as
pretty. There was an interesting NASA display at an Oshkosh once.
Actual crashed fiberglass structures; slow-motion video of their
tests. Composites flex very considerably, before tearing the cloth,
giving the final appearance of the plane just "breaking" in places.
After seeing all that, I concluded a flex line at least at the tank
connections might be best. But I really don't know for sure!
