Brunswick QCS-12

QCS-12 represents the evolution of technology through the history of Brunswick's Quantum series of bowling balls with the identifiable mushroom-shaped core. The mushroom-shaped core found in this ball has been modified to include flow-through channels that allow DynamiCore2 to move into the core which helps with adhesion as well as durability and the ball's hitting power. The technological advances with this ball introduce DynamiCore2 which creates the same thick shell effect without the need for an actual thick shell allowing easier revving and more versatility. The QCS-12 core is the original mushroom-shaped core that has been modified, this core has a lower intermediate core value that is more round and continuous.
