Ebonite

Drilling #1

• Ball Reaction: Long & Strong
• Suitable For: Most styles and target lanes
• Flare Potential: Medium High
• Center of Gravity: The center of gravity placement may or may not fall inside the CG area. If it does not, then the balance hole location may need to be adjusted.

*Mass Bias Placement: Place Mass Bias 3 inches to the right of the thumb hole. If needed, place balance hole 4 inches over and 1/2” up and drill back to statically legal.
**Mass Bias Placement for HIGH REV PLAYERS: For players that have RPM rates of 350 and greater, you need to place the Mass Bias Location in the 70 to 90 degree location.

Drilling #2

• Ball Reaction: Long & Strong
• Suitable For: Most styles
• Flare Potential: High
• Center of Gravity: The center of gravity placement may or may not fall inside the CG area. If it does not, then the balance hole location may need to be adjusted.

*Mass Bias Placement: Place Mass Bias at a 45 degree angle to the right of the thumb hole. If needed, place the balance hole over on the Vertical Axis Line and 2 inches down and drill back to negative side weight. The bigger and deeper the hole is, the stronger the ball reaction will be. Remember to keep the ball statically legal.

Drilling #3

• Ball Reaction: Early & Strong
• Suitable For: High Ball Speed, Low RPM’s, Heavy Oil Patterns
• Flare Potential: Very High
• Center of Gravity: The center of gravity placement may or may not fall inside the CG area. If it does not, then the balance hole location may need to be adjusted.

*Mass Bias Placement: Place Mass Bias in line with the pin. If needed, place balance hole over on the PAP and drill back to statically legal.

• Center of Gravity: The center of gravity placement may or may not fall inside the CG area. If it does not, then the balance hole location may need to be adjusted.

*Mass Bias Placement: Place Mass Bias at a 2:00 direction from the center of span. If needed, place balance hole 8 inches from the center of span in a 2:00 direction to remove excess positive side weight. Place balance hole 6 inches from the center of span in a 8:00 direction to remove excess negative side weight.
