Does BK2K default to 5 balls? That would explain why I have such a hard time of getting more then 3-4M with any regularity. That game is BRUTAL if you lose control of the ball or miss a shot on the lower play field.
I don't really like 5 ball games typically. Older EMs with short ball times—especially Gottliebs with the wee flippers—make sense on 5, but games where you can trap, post pass, nudge balls out of the outlanes etc. tend to seem a bit easy.
