Do you have a game that you just seem to kick it's ass when it's multiball time?
Mine used to be FH, but I think it's Rollergames now. It's far from every time, but many times I can cradle a ball on the left flipper and continue to hit the pit with the other ball, then hit the wall ramp once the vuk fires the ball over and after it gets released back to the right flipper repeat the cycle. There are nights that I can't hit it, but then some nights I can do it more often then not.
What's the pin that you do well in multiball?
