This one! Which I just, coincidently, scored my PR. I rolled the Points and Score for 8 replays! I was also rated a 'genius' on the back glass . I'm not going to argue, I played that thing like a fiddle.
Pro Pool is my longest owned pin, I think. Almost sold it but when the person backed out I was very relieved. It's like a shooting gallery with all those drop targets. They keep resetting too! I haven't played the others but PP is an excellent player, has a great theme, campy art, has aab play (which adds diversity in an em collection)...a keeper.
