The last few pin shows I have been too I am seeing damage being done to the new STERN pins with the metal back boxes. Two ways the pins are being damaged are #1 the two rubber plugs at top of back box that are "supposed" to prevent back box from rubbing on rails, slide to the side during transport causing damage (SEE PICS) and #2 when you lift up play field and rest it against back box, the apron is scratched, mostly with LE models and pins with metal aprons (this probably applies too other non stern pins). So when you lift those play fields up get a blanket up on that back box or when you transport your pins get a blanket on there or rubber matt. Hope this helps you all out and saves your pin from getting damaged. Sorry if I double posted.
