I took the upper left orbit gate out of WPT, per the suggestion of the designer. Many others have done so as well.
I also added a deflector to the POTD exit in LOTR. Even though Keefer maintains the random dropping ball design was intentional, I far prefer the smoother/faster flow and prevention of ugly bounces, playfield dings, broken plastics etc. to scoring a few inconsequential souls if the ball bounces into the shire.
