Just a few things I would like to address. First, I had the opportunity to be part the the testing market for the new Prov1x and want to thank Titleist for selecting me. Recently I attended a Ball Fitting clinic at a local golf club in Central Florida. Since I currently use the Prov1x the ball fitting validated by choice but I want pass on how well the Balling Fitting staff conducted the clinic. They were very friendly and knowledgeable. A job well done and they need to be recognized for their performance. Finally in examining my test ball and previous editions I see no visible difference in the ball(e.g. stamping or markings). Question will the new ball be subject to the "one ball rule"? I as well as others would hate to play an event and get confused trying to determone which is a newer version.
