In this video, 2nd Swing tests the Pinnacle Soft vs ProV1 and ProV1x at 109 MPH swing speed. They said Acushnet told them that the Pinnacle Soft basically meets the proposed rollback requirements.
Executive summary: Pinnacle spun 400 rpm less, actually too little for the guy, and it flew lower. It had a bit less ball speed, and 11-12 yards less carry. Roll out took it almost as far as the premiums.
There must be other soft balls that are about the same. I wonder how many people who are angry about the proposed rollback are already playing a ball that meets the proposal.
