How many balls do you EM guys usually set your games to, this one was set to 5 balls but I almost triple clocked (sorry Nick, I pushed your initials out from the high scores  )

Depends on the EM... in all honesty some 70's EM Gottliebs are ball drainers straight down the guts between the flippers ( centre spinners or drops are a bad design)... these are set on 5 balls.
From recollection GTB TOP SCORE is the only game ive ever owned where i shot all 5 balls and didnt get to touch one of them with a flipper!

Sounds like VOLLEY is  a great game ... ive never yet played one, but with scores like that on 5 balls id be dropping it to 3
