Powrkoil 18™ coverstock is a proven performer in the bowling industry. Aggressive in the oil and strong off the dry, Powrkoil 18™ is a perennial favorite among all styles of bowlers. The Karma™ uses a solid version of Powrkoil 18™ which provides more mid lane traction for a smooth continuous backend motion. The Karma™ incorporates a familiar light bulb shape Medium RG Performance core that provides easy length through the heads, midlane stability while maintaining axis rotation for a strong continuous backend motion. With its High Gloss box finish, The Karma™ will provide good length through the heads, a medium response to friction in the mid lane with a smooth controllable backend. The Karma™ is great ball for rev dominant and slower ball speed players on medium to light oil conditions. The Karma™ can be drilled using the standard drilling techniques developed for symmetric bowling balls. At Brunswick, the unique core shape of each individual ball is used for weights from 12 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range.
