Track introduces a powerful new direction in Pro Performance with the Synthesis. Built around the debut of I-Core Gen4, an evolved take on the iconic I-Core series, Synthesis delivers increased intermediate differential for a sharper breakpoint for a big-ball. QR-12 Solid additives in the HK22C base help the new I-Core Gen4 produce an aggressive overall motion that Track fans have been craving. It sits perfectly between Theorem Solid and Paragon Shadow, strong enough to control heavy conditions yet not so early that it loses power downlane. On fresh oil, Synthesis stands out: confident traction in the midlane combined with dynamic continuation that keeps striking. When the pattern calls for a true heavy-oil weapon, this is the ball you want to build your game plan around.
