Performance Index
PRO:
Brunswick’s most advanced technology. The strongest core and cover combinations we offer.
FLIP:
Balls that skid through the front part of the lane with the strongest change of direction down lane. Balls with higher numbers will have a stronger change of direction.
REACTION SHAPE STRENGTH: 80
The higher the number the stronger the reaction shape – with 1 being the least and 100 the most.

Quantum Bias Pearl Cores
The Quantum series has been designed with 3.5 times more coverstock for improved durability, performance, longevity, and incredible hitting power. The enhanced Coefficient of Restitution results in the pins flying faster for greater pin action and more strikes.
Drilling Instructions
Brunswick provides general purpose drilling layouts which will apply to every bowler differently based on multiple variables. These variables include the bowler's ball speed, rev rate, axis rotation & tilt, and lane conditions. All or most of these variables should be known so that the best possible layout can be chosen for each ball. We recommend that you contact your local Pro Shop Professional for more detailed layouts and how to apply them to your game for each ball in your arsenal.
