I agree with everyone on the flipping before the magnet releases.
My pro always drained sdtm off the prison magnet until I read about doing this with the flipoers.
However I noticed the magnet was slightly lower than the playfield the other week.Took the Assembly out and got that loctite nut off.
Put it back in the game,adjusted the height and now instead of sdtm drains it now throws the ball towards the prison.
It is like its turned 180 degrees throwing the ball.
