We all seem to focus on the size of corner pockets when trying to make a table play tougher. Side pockets are traditionally 1/2 an inch wider than corner pockets but I am suggesting that all 6 pocket openings should be the same size at 4.5 inches. Not as many balls would go in the side making the table play tougher. At the same time, maybe that would take some of the focus off making the corner pockets too small for pool. (You shouldn't have to baby a well struck ball down the rail to make it go in.)
