For anybody getting a Premium or LE Metallica who is thinking of the scoop hole protector ...

It might pay to wait until the machines are actually released as the protector screws to the underside of the playfield . On the Premium / LE model there is a subway trough that feeds the ball from the coffin lock across to the scoop hole . It might be worth waiting to see where / how the trough mounts in that area first in case it gets in the road of the protector screws etc .
