I tried to lead this yesterday. First piece is a solid green c3 in the first horizontal to protect the dead point. Serious decking potential while placing the next pieces in the next horizontal. There I got a #2 Ballnut and a #1 WC nut but the nut will fly out if pulled to the left or the right. To the right of the nut goes the BallNut but when I placed it ball up and took on it it started to slide, ball down looked better. Above that is another #2 ball nut in a bad upward horizontal position after doing the layback crux, not sure if it would take a fall but is probably ok to hang on, the climbing is much easier there however. Probably will be X rated.
