Some of us try our best! I think my pins on location play great for what they are. Most of them are players and heavily routed, but in good working order!
I do put some of them on a very slight lean if it seems to favor draining on one side or the other to balance it out. Players seem to enjoy playing longer than usual. Sometimes I adjust the flippers to make certain important shots much easier. They’re my games, and I want people to enjoy playing, rather than get their ass kicked and walk away. Only negative is regulars blow them up and get tons of replays.
