Brunswick True Nirvana Bowling Ball
The new ECS Hook Pearl coverstock is Brunswick’s latest advancement in performance enhancing technology. ECS expands the soft segments of the polymer chain producing improved friction and wider sweet spot resulting in fewer adjustments. ECS technology generates a faster refresh rate and a longer performance life for the coverstock. Merged with the Nirvana Ultra Low RG core, the True Nirvana delivers the strongest backend ball motion in the Brunswick line for oily lane conditions.
The True Nirvana can be drilled using the standard drilling techniques developed for asymmetric core bowling balls.
At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
