A wire in the LE is too stiff, try a light piece of braided cord and a SMALL AMOUNT of poly glue. Just enough poly glue to anchor the cord but not enough to make it a rod. This could help a lot in preventing the tearing coro has experienced. Its a cheap enough experiment any way. The thought is to spread the impact force as the soft foam LEs do. hmmm Even in 2MM coro small nylon string could be employed in as many as four flutes at the wings LE area?? just thinkin' out load here I guess.
