The Precept PWR Drive is the average amateur's dream golf ball. Extremely long and straight drives are a frequent occurrence with this advanced golf ball. The construction is a 3-piece marvel boasting 432 aerodynamic dimples for a piercing trajectory. But, that doesn?t mean much to the average amateur. The real action is in the newly developed PWR Dynaron Inner Cover. By utilizing the rubber technology incorporated into Bridgestone Grand Prix racing tires to keep them strong yet soft enough to hug the turns, the engineers have created an inner cover that forces this ball to fly long and straight down the fairway. Combined with the delicate PWR Muscle-Fiber Core, this ball maintains incredibly soft feel. The result is a happy amateur.
