I have a friend that has a Diamond 4 1/2 x 9 table that has very tight pockets. I didn't measure them, but I can attest that they are the tightest I've ever played on. He's having his table re-felted in August and I asked if he was going to have the pockets opened up a bit. He said he had considered this but someone told him that they would have to cut back the cushions to do so. I set up a few of my own tables years back (always Brunswick tables) and there was enough play in the positioning of the cushions so that the pocket width could be varied by moving the rails in or out a bit. Possibly there is a single position where the rails are supposed to be set, but I know on those tables the pockets could be opened or closed a little by repositioning the cushions. What is the correct way to open up the pockets a little. Is repositioning the cushions out a little acceptable? Thanks for any information you can provide.
