Will TITLEIST again be the number one ball used at the Masters? If the new Prov1 and Prov1x have been tried by the Pros, my opinion is that it most definitely will be. I, personally, have been using the new ProV1x and it is one of the best, if not the finest, ball on the market to date. It even outperforms the older ones and that is some kind of improvement in ball technology.
