I had tspp, Lott, and woz. I ultimately parted with tspp. When I want to play a deep ruleset I go for woz and Lotr is a family favorite. The more you understand the intricacies of Woz the more it shines.
I tell people you have to nudge the machine anytime it is near the top of the slings. Give it a try. It we increase your ball times dramatically.
The rules allow for a ball saver but it is not a default setting. Bummer that the operator does not give it at least 5-8 seconds to prevent house balls.
