Recommended Layouts for EXPERT Ball Drillers
Pro-CG bowling balls are often utilized on the PBA Tour and have helped out Pro Staff achieve great levels of success. You, too , can reach the pinnacle of your game with this very dynamic piece of equipment. Please refer to the layout options to determine the best for your needs. Good luck.
Because all bowlers have different Positive Axis Points (PAP),your layouts may not have the same appearance as those illustrated below.
The following layouts are for right-handed bowlers. Remember to flip or rotate to produce "mirror-image" for left-handed players.
Leverage - No Hole
- Place the pin 3-3/8" from the PAP to product maximum flare.
- Locate RAD in the STRONG position, halfway between the ball track and PAL
- Be sure to check for excess side weight, as a balance hole may be necessary to make the ball legal
Low Pin - Low Hole
- Place the pin 4-½" from the PAP under the fingers.
- Locate RAD on the axis midplane.
- Place extra hole on line from the grip center through the CG 1" inside the PAL
High Pin - No Hole
- Place the pin 5" from the PAP above the fingers.
- Position RAD 1" left of the STRONG area (be sure to allow at least a 2" buffer between ball track and RAD!)
- Be sure to weigh the ball for static balance. If necessary, remove excess finger weight - drill the finger holes very deep.
Low Pin - Large Hole
- Place pin 4-½" from the PAP below the fingers.
- Position RAD 1" left of the STRONG area. (Be sure to allow at least a 2" buffer between the ball track and RAD)
High Pin - Large Hole
- Place the pin 5-½" from the PAP above the fingers.
- Locate Rad in the STRONG position.

- Locate the RAD 2" right of the ball track, just left of the STRONG position.
- Locate large balance hole on PAL.
