As a rule, the tilt bob stays in the game and is set to a reasonable senestivity. I always replace missing tilt bobs when I get a new game. How come that part is always missing in games for sale???? Anyway, having it removed seems like you are only cheating yourself. It is almost as bad as adding a post in the flipper drain which was done on my Bride of Pinbot by a previous owner. I could of killed him when he told me that. The guy was so proud of his accomplishment. He honestly thought he added value to the game by adding that darn post.
