Using the diamond system is like painting by numbers...it should not be a part of the pro game whether it be in pool or caroms. I say this more because they are essentially useless anyway...top carom players don't use them...neither do top pool players. It gives the impression that anybody can just learn the diamond system and have success....kind of like cte lol. It just makes a mockery of the game.
