About those dimples...I learned to view them as a guide. Most of the time they are in the correct spot. On High Speed, there are three sets of 3 targets. They are not in a "bank" but individually attached to the bottom of the playfield. One would think the dimples would be in a nice straight line and properly centered in the cut-out in the playfield....not so. When I asked CPR why they would not make them right they replied, because that was the way they were on the playfield they used to map them. In another case, don't recall the game, the left flipper mechanism was way too close to a light socket...I mean right up against it. I rotated that flipper mechanism to a much safer orientation....
Just food for thought.
