Hey guys - just finished shooting a short video for Mantis that goes over the improvements that the Mantis 6-ball trough has over the OEM version. I thought it might be useful for any Pinsiders that weren't sure what all the fuss was about - or didn't even know this existed.
This part isn't necessarily new, but has long been described as a WPC-95 trough. In fact, it works with any WPC game with a 6-ball trough (AFM, STTNG, MM, ToM, CV, etc.)
