I think I have a sleeve of the balls remaining that you are referring to. It has a white box on the sleeve with a small black dot in front of the Pro V1. The same marking is on the side of the ball. Maybe this a higher compression ball. I have had trouble hitting this ball in the air with my driver and it seems to not go as far compared to the others in my group who I play with regularly. I am normally as long or longer off the tee as my playing partners but not with this ball. Any ideas about this ball?
