The Mastermind Strategy combines the Relativity Solid Reactive coverstock with the Modified Mastermind Asymmetric core for a ball motion that is very similar to the proven performance of the original Mastermind. The blue/violet/orange Mastermind Strategy offers strong and controllable hook motion on medium to heavy oil lane conditions. The Mastermind Strategy 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.
