I'm sure that they moved IM to 5 balls because it would be frustrating for the average player because of quick game times. Maybe they overcompensated too much by closing the out lanes. Too bad you did not like it, it is one of the newer Sterns that I do like.
Agree with you on the EM games they have. Pop(Drop)-A-Card brings back fond memories of a game I pumped quarters into as a kid. Loved playing it there last year.
