I am having trouble opening the rack with the break shot using a Measle Ball playing 14.1. On similar break shots using the Red Circle opening the rack has not been a problem. I think the Measle Ball is denser but grittier on the surface which doesn't allow for the ball to drive through the rack. The Red Circle seems to glance off the object ball more creating separation in the rack. I know the Measle Ball is more difficult to draw but I am not sure what the physics of this situation are?
