I finally got through my old ProV1x balls and yesterday, put a new ProV1x into play. What an awesome ball. Definitely flies further and stops on the green. Best of all, on the driver, and irons I could really feel the ball compress and explode of the face. On wedges I could feel the spin imparted by the face. And, the putter was soft and rolled well; of course making a 40' birdie on the fifth hole does help!
