Notes
Another versatile ball for me. This is my first ball out of the bag when I go to my Wednesday league because I can easily control the motion but it also allows me to open the lane up before going to something a little bit cleaner when I start seeing carry down. This is another interesting ball to go to when the asymmetrics are too much ball but I still need to pick up the pattern.

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.
