Don't get ball Envy.... Introducing the new Hammer Envy. We introduced the Launcher Asymmetrical core with this release. The Launcher has both a flip block and radial disc technology. These components move mass from the center, creating increased imbalance for a stronger reaction throughout the lane. Pair that with the Envy Solid cover and you have a legit hook monster! The Numbers RG: 2.514 (15 lb.)DIFF: 0.048 (15 lb.)FINISH: 500, 1500 Siaair Micro PadAVAILABLE WEIGHTS: 12-16 lbs. DOT Technology A truly innovative approach to bowling ball construction, DOT pins the low RG axis on the opposite side of the ball. This removes the weak spot in the drilling area, greatly reducing the possibility for cracking and providing for a wider range of layouts.
