Brunswick Knock Out Bruiser Bowling Ball Review

The Knock Out Bruiser is the latest Knock Out ball to join the Brunswick family. All three of the balls in this line have used the symmetrical Melee core, and this one further evolves the Savvy Hook coverstock family by introducing the SH 4.0 Solid formulation.

The cover was dull enough to give the ball a strong overall hook without starting up too early, which gave him good pin carry and made it easy to adapt in transition. He simply made some 2-and-1 moves inside when the ball crept high, and the Bruiser had no trouble handling the oil or reading the breakpoint. Very late in the session, when the Bruiser started to lose some angle downlane, he could get into the Attitude or Melee Jab Carbon to retain more energy and get through the pins again. The dull box finish had enough texture for Tweener to get to the pocket on the heavy oil test pattern. He needed to close his angles compared to how he attacked the medium pattern, and he also needed to be a little softer with his ball speed. Later in the session, as more friction developed, he could go
