My wife has started making wing bags after it has become clear that the world doesn't need COBOL programmers any more. She has made the first run of bags that I will carry to the ESL contests to show.
She offers a set of Mantis bags (any variant) where each panel has a separate bag for $100, or just the tail covers for $25. She also offers a single bag with compartments for all panels, which is quite a lot more expensive, at $200, because of the labor involved.
If the bags aren't exactly what you need, let us know. We will appreciate any help getting this tiny business going.
