Track continues the popular Kinetic series in the Track Kinetic Obsidian. This ball features the modified Kinetic core which has a low RG, medium differential, and low mass bias. These components allow this ball to save its energy longer but use it quicker. Track has combined this core with a solid version of the DR-7 coverstock which gives length with a strong reaction at the backend. With a 500/2000 grit finish this ball is recommended for medium to heavy oil patterns. This mid performance ball with a mid performance price and an asymmetric core is hard to beat.
