|The Columbia 300 Authority high performance bowling ball features a modified version of the ERT coverstock called the ERT 2.0 Pearl coverstock. The original ERT coverstock was used on the popular Baller but additives were used to create more down-lane motion in this version.

All colours do vary somewhat from the picture shown.
