900 Global Drilling Pattern Selector
In order to accurately determine a drilling pattern and final ball surface, you must first identify your personal bowling characteristics; these three key factors must be determined.
- Bowlers Ball Speed
- Bowler Rev Rate
- Bowlers Axis Angle of Rotation
Chose the number below in each category that best describes your bowling style.
- Ball Speed 1 = slower, 2 = average, 3 = faster
- Ball rev Rate (RMPs) 1 = cranker (18 or more), 2 = tweener (13-17), 3 = stroker (12 or less)
- Axis angle Rotation (side roll) select from one, two, or three
Step 2: Total your numbers up from ball speed, rev rate, and axis rotation. Use that number to select your drilling pattern.
Step 3: Layout must be based on your Positive Axis Point, illustrations are all based off a 5-1/2 over PAP.
Step 3: Choose your lane condition.
Step 4: Adjust surface.
