According to the article above, the new Titleist Pro V1 and Pro V1x are "demonstrably better" than the 2021 models due to a new high gradient core design on the ball. Frederick Waddell, Director of Golf Ball Product Management said, "For a Titleist golf ball to be new, it must be better." The reimagined core update was designed to be firmer on the outside and progressively softer on the inside, which promotes fast speeds, low long-game spin and tighter dispersion while maintaining high levels of greenside spin. While several innovations from the 2021 models remain in the 2023 models, the new inner core of the Pro V1x's dual core increased in volume by 44%. This increase in volume helps the stability of the ball through the air and ensure a long and consistent flight. The new model has already been used by 45 pros on the PGA tour, including Will Zalatoris, Viktor Hovland, and more. The improvements to the ball have been noticeable to pro golfers so far. Zalatoris said, "When I switched to the 2023, I actually gained a little bit of distance with the driver and it was actually better through the wind." The evidence stands to argue that the 2023 Titleist Pro V1 and V1x are in fact "demonstrably better" than the 2021 models through improvements and better design.
