Hit the Deck is a bit too posty ,
most shots from the flipper end up hitting a post as opposed to desired target or KOHole
(i.e. refer to Cactus Jack's comments). Also a bit pricey.
C37 shots a bit more satisfying, but again game probably priced out of range for most.
Big Hit is most affordable and has lots of drops. So Big Hit is my choice for you.
