The 920A was designed to be more Angular on medium/heavy oil patterns. Built on the LEGGO core platform, the designers modified it by raising the RG to 2.57 and tweaking the horsepower of the core (Intermediate Differential) to .020, thus gaining extra length while still having plenty of hitting power. The coverstock chosen for this ball is the HP Gen 3 with Performance Pearl. The Pearl helps to make it more Angular on the backend. The surface is 4000 grit Abralon® sanded. Each new ball from Track will include a microfiber cleaning pouch with instructions on its use.
