I didn't see a search function on here as I'm sure this topic has been brought up a time or two, but what is the difference between the Red and Blue Diamond Pro-Am tables? I played on a 9' with the blue Diamond logo on the rail at Kromes Billiards in Little Rock, AR and then this morning I played on a 9' with the red Diamond logo at Cue and Cushion in St. Louis, MO.
