I d/l this from Trckbowling.com (Rising drill sheet link)....
Track Rising Basic Drilling Instructions
The drilling instructions included are specifically for the Track Rising Ball. The basic layout has been developed to simplify ball reaction for average bowlers. Inside you will find step by step instructions. If you need to adjust the ball reaction after the ball is drilled, checkout Abralon pads as adjusting the surface of the ball can change the reaction by a large margin. For more technical layouts including 360 technology go to HYPERLINK "http://www.trackbowling.com"

get a code to unlock all the special drillings. The basic layout illustrated provides big hook with strong continuation.
