Introducing the Momentum Swing from Columbia 300. This High Performance ball features a new shell (NE2MaXX) that is combined with a modification of our proven Resurgence core. We simply shaved off two edges giving this core an asymmetrical non mass bias look. This core and shell combo will give every league bowler the right combination of control and carry for today's competitive environment. Positioned in between the Resurgence and Momentum in terms of both total hook and overall performance, Momentum Swing is the right choice for medium to heavy volumes.
