Propel is a revolutionary coverstock developed by Brunswick to improve the midlane and backend traction of the ball on today's slicker oils and lane surfaces. The Propel coverstock was discovered through testing of new formulation additives and process changes in coverstock manufacturing. The Wild Splash uses the popular Zone Classic lowRG asymmetrical core shape system. The core improves the adhesion of the Propel coverstock to the lane, giving the Wild Splash the potential to aggressively respond in the mid and backend of the lane. The core and coverstock combination found in the Wild Splash creates a clean frontend, strong midlane recovery with a powerful and continuous backend reaction. Bowlers looking for an aggressive but forgiving backend reaction will appreciate the Wild Splash. Most bowlers will find success with the Wild Splash when combating medium to oily lane patterns. The Wild Splash can be drilled using the standard drilling techniques developed for asymmetric bowling balls. The unique core shape of each Brunswick 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. The same drilling instructions can be used for 12and 13pound balls. This is because Brunswick uses a generic core shape with an RG diff erential that is close enough to the 1416 pound shape.
