The Absolute Nirvana combines the Nirvana Ultra Low RG core with our new ECS Hook coverstock to produce strong mid lane traction with outstanding continuation through the pins on heavy oil lane conditions.
The Absolute 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.
