During a tournament where a slightly finnicky Starship Troopers was involved, I did a bit of pre-game coaching. I told the other 2 competitors that if multiball starts, manually plunge those balls. The ST in question sometimes gave weak kick-outs from the plunger lane, and due to the design of the lane, it drains out. 5 minutes later the other competitors were manually plungin' and kept on trucking.
