Quoted from seshpilot:I thought TZ was 6 balls (5 steel and 1 ceramic)? That's what my manual says
The game was originally designed for 7 (6/1) balls, shortly after samples were out, they dropped it down to 6. (5/1) My game still had the 7 ball sticker on the lock-down mech, and it was torn up, so I had Flash make me another. (And yes, I do put 7 in mine.)
The normal set that he sells (like he mentions) comes with the 6 (5/1) decal.
