The No Rules Pearl is amazing. I drilled mine 4x4x2 and my PAP is 4 5/8 x 11/16. I play 35 to 5 and what I love about the No Rules Pearl is that when I am playing this line the ball is not overly aggressive it has a smooth controllable, predictable and easy to adjust break point. If I miss inside the ball reads well and does not overreact, she sits inside and still commands the pocket as if I played way outside. The one thing I look for in a bowling ball for me is how well does it read the middle part of the lane. This ball reads the middle part of the lane amazingly and if she finds a dry spot she continues through until she is supposed to hook. I drilled this up and out of the box I shot a 300. Over the last 8 days of bowling and 2 tournaments I have average 244.72. This ball is a must for all bowlers and you will not be disappointed. I wasn’t.
