Despite a redesign of the input conveyor last December for my Lift & ZigZag Great Ball Contraption module, it was still proving to be not reliable enough, but I had been putting off doing anything about it. Wih several shows looming where I needed to take GBC to display, a few weeks ago I gave it some more thought and decided to completely rebuild the input side. I had found a GBC Workshop module design online (WM01 by Matt Norman).
