You should have a good sampling of as many of these later pins as possible: XM-LE, Tron, ACDC-Premium, IM, SM, TF, WOZ, LOTR
though I'm not sure how well something like LOTR does on location with such long games.
Then move on to top rated pins... with consistently solid attract value like MM, AFM, WH20, TSPP, FG. Older SS/EM games tend to sit idle more than DMDs, but provide a cheap way to round out a collection of 14 pins.
