The Code Black is one of the most versatile balls I have thrown in quite a while. I drilled the ball stack leverage and the results I got were amazing and not what I expected. I was expecting the ball to aggressively snappy. This was quite the opposite. I found the ball to be very forgiving. The Code Black actually had a very controllable hook all the way through the lane. The Code Black was very clean threw the middle part of the lane which I love to see and amazing hook. I played 30 to 7 and 30 to 12. When I played 30 to 7 the Code Black tracked out nicely grabbed just past the middle part of the lane and rolled smoothly into the pocket with amazing pin reaction. When I played inside 30 to 12 the Code Black read the lane with ease and realized that it was in a lot of oil and when she reached the back end I did not get a snappy hook result I got again a smooth flush and powerful reacting pin reaction. Even when I missed outside 7 and hit 2 to 4 board she did not go haywire and snap across the lane, she reacted very well and still managed to reach the pocket (Tad Light Obviously) but still carried. This ball is so versatile you will need this ball to compete at a great level I think. This ball opens so many doors on the lane it is unreal. My PAP is 4 5/8 X 11/16.
