As a female bowler, I favor asymmetric weight blocks to give me the added flipping power that I do not generate in revs. I was able to get 10 boards deep than my other most aggressive ball. Had it punched up pin down which allowed me to open up the lanes and get out of everyone's track. Out of box 667 during tournament play. If you want to open up the lanes, this ball is incredible on the lanes and with the elastic core powers through the pins.
