Does anyone know why Diamond 7 fters, Blue Label is all I’m familiar with, slate measurements are at least three different sizes when measured diagonally. This occurs on tables all made within the last 2-4 yrs. The pocket (shelf) is so deep on some that when a ball is in the very jaws it can not be made fairly (no going to the rail first without hitting opposite point on the way out). And no hitting ball first without a draw shot, which can’t be done on some angles. Seems like it prevents play as pool was designed. If you haven’t measured this way you should.
