Performance Index

Brunswick’s most advanced technology. The strongest core and cover combinations we offer.

Balls that hook earlier on the lane providing more hook on oilier conditions or for bowlers with lower rev rates. Balls with higher numbers will have more overall hook.

The higher the number the stronger the reaction shape – with 1 being the least and 100 the most.
