Drilled my maxxx 55x3x25 with a p3 hole obf. I am  low rev high speed type of bowler. Played it in a house with weak  backends. I was able to roll the ball all 3 games 203/188/197 in a house  i average just 184. played down the 8 board this ball hits the pocket  hard and was still bringing oil back at the end of the 3rd game. This  ball is a keeper. good job Lane # 1
