I`d be interested in knowing more on the mast weight & its ability of memory (or lack thereof)
Mike, this is also directed at you, as you already have the section.
As I understand it, the pre-bend is forward, not back. It allows for more tension on the backstay and therefor the forstay without putting a lot of curvature in the main luff and flattening it out. Ideally, the prebend would give you a tight forestay and a straight mast.
