Talking about a rack which gives a breaker an advantage ? Don't know, but I've heard if you put 2-ball in the 4th row and the 3-ball diagonally on the second row, it will statistically give a harder run out for the breaker. With this layout 1-ball and 3-ball will be around the same area and 2-ball in the other end of the table.
I think Mike Sigel introduced this to my knowledge but don't if it was his idea. Never made any research if this layout of balls will make a difference...
