    Are you saying you laid the inner ply parrallel to the spar so the outer ply ran from spar top to spar bottom?

    That's correct. I should have been more specific. That inner ply stays relatively dry and stiff while the outers are nice and limp, and so the sheet will bend around the leading edge more easily with outer grain chordwise.
