Brunswick Defender
The Defender has an updated version of the original Prism core. We've added a dense "donut" to the bottom of the core that moves more mass away from the center of the core, creating more continuous movement toward the alley. Further, this also creates a slightly higher RG and more overall differential, which also improves movement in the backend. The Defender features a new version of our A.C.T. Shell material engineered to generate more traction in the middle and back of the track. This core/cover combination gives the Defender better distance compared to balls like the original Prism, but with more taper in the back of the lane.
