So with the leech all twisty and venting off excess power, up top, and also accounting for apparent wind up top...

What happens if we let the sail twist off alllllll the way down, say, even past the boom? (if I remember correct NP had a sail that sorta does this already)

Could you develop a sail with massive wind range? Would it be too soft and cushy? Could you get away with ...one sail?

Just stoking the camp fire there.
