Quoted from chadderack:If I have any negatives, it's about the geometry.
At least 50% of the time, coming out of the pops the ball is SDTM. I can bop the machine right when the ball hits the lane guide (on the left) coming out of the pops... but that is often ineffective. At least half the balls I get (even with ball save) are house balls.
The rules are good, IMO.
Put a oversized rubber on the post on the left side of the bell lane exit.This helps send the ball to the right slingshot.
