Quoted from DCFAN:
I saw one person post the Spidey Sense mod. They had to cut an opening in the metal ball guide so the ball would go to the shooter lane. When I saw the need for cutting I said no to that mod. I don't want to do anything that is not reversible on my games unless it is a universally expected/acceptable change. Maybe if replacement ball guides were available I would do it, but they are not.
Here is a link to the mod (scroll down to pinsider Dug):
I do not think that I like that one.
