Columbia 300 Dynamic Swing Bowling Ball Features:


The Dynamic Swing is a hybrid-covered asymmetrical release from Columbia 300. Its ERT Hybrid cover is the same as what was used on the Baller, although this version is from a different manufacturing facility. This coverstock comes out of the box at a rough 500/2000 SiaAir finish, which helps the Dynamic Swing create plenty of midlane traction. The core design is modeled off the Pure Swing release from 2010 but with a lower RG and differential, and it now also features both the DynamiCore and DOT technologies. Comparing this release to older balls under the “Swing” nameplate, the Dynamic Swing’s motion is more reminiscent of the Momentum Swing than the Pure Swing or Full Swing releases.


It has been a priority of Columbia 300 to evaluate the cores, covers, and names from the past to make sure they give the Columbia 300 fans what they want. Columbia is excited to introduce the Dynamic Swing, featuring a modified Full Swing core. They have combined this popular core with ERT Hybrid, and left it dull to handle any medium to heavy oil condition.  

The Dynamic Swing’s medium asym numbers and hybrid cover complements the Authority Solid and original Authority perfectly.  Medium hook, overall hook between both authorities.  Sharper breakpoint than Authority Pearl but sanded finish helps it handle more oil.
