Can't seem to find pocket reducers if that's what they are called. Have a new 8th. Brunswick with big pockets. I don't want permanent change, which I think would be shimmed? I have seen these portable type reducers that attach some how. Brunswick site offers nothing I could find. Table is just way to easy to play. It's not my table it's my brothers so I don't want anything that will mar the pockets. Am I dreaming, or is there such a product?
