- From the manufacturer
The Counter Attacks cover uses the Ai-20 formulation, it is the same exact cover formulation used in the original Rack Attacks. The core design is very similar, we have made a few subtle changes in order to enhance the continuation through the pins making a better version of the original Rack Attacks.
- Status
- Retired. This ball is no longer produced by the manufacturer, but it may still be available at pro shops and online retailers in limited weights.
