On the FJ community someone posted this picture and was asking what kind of balls these were. Obviously they are Prov1x. I am sure he wanted to know if they were test or prototype balls. There were many guesses and one even pointed out that these were made for the pros. Can the experts give me the correct answer. They look like the balls that you guys send out for us to test. One ball marked differently so we can compare. But I want to know from the experts. Thanks, Chuck
