That was what the rubber bands were for - keeping the stand offs in place on the sail's trailing edge!! Wouldn't the drop of cement keep them from being moved from hole to hole?? That was one of the selling points of the kite, that you could tailor the sail's shape to the wind and your flying style by moving the stand offs to different positions!! I, myself, agree with your solution, I've used the same position for my stand offs for years!!
