John, You are exactly correct. No matter how much you tighten the wire, there is really no way to prevent the deflection of the luff. And the problem that I can see with the CDI system is that when the wire is tightened all that load is transferred to the fasteners holding the bracket on. As I said earlier, there is a stronger way to do it by modifying the gooseneck and bringing the wire down to a proper termination like a tang somewhere below the boom. But you will still have a lot of deflection in the foil.
