Track Synthesis Bowling Ball The Synthesis is a powerful new direction for Pro Performance that Track has introduced. Synthesis is based on the release of I-Core Gen4, which is a new version of the classic I-Core series. It has a higher intermediate differential for a sharper breakpoint for a big ball. QR-12 Solid additives in the HK22C base help the new I-Core Gen4 move in a way that Track fans have been wanting. It fits perfectly between Theorem Solid and Paragon Shadow. It's strong enough to handle heavy conditions, but not so early that it loses power downlane. Synthesis stands out on fresh oil because it has good traction in the middle lane and keeps hitting with dynamic continuation. This is the ball you want to use to build your game plan around when the pattern calls for a real heavy-oil weapon.
