Bryan,
Just had to put my 2 cents worth in, Brando hit the nail right on the head unlike most heavy oil balls this one does not over react on a medium condition and the carry from the ball is almost too good to be true. As an example my son used it for the entire matchplay in the Sun City Open in Townsille just recently and averaged just under 211, not a bad average. But something else to consider the boy is only 12, yes he is left handed which does not offer a true reflection for the right side of the lane but I dont think he moved more than 5 boards total to the right during the matchplay. Personally I think this is a must have piece of equipment but that is just my opinion
