Titleist is offering an all new Pro V1 and Pro V1x for 2021.
Both models have a new softer Cast Urethane Elastomer cover that increases greenside spin and control. They added a faster casing layer which increase speed and lowers Long Game spin. The core was reformulated with their 2.0 ZG Process Core to increase distance.
The Pro V1 has a new Spherically-Tiled 388 Tetrahedral Dimple Design that produces a more penetrating and consistent flight.
The Pro V1x V1 has a new Spherically-Tiled 348 Tetrahedral Dimple Design that produces a higher and more consistent flight.
The Pro V1 feels softer, flies lower, has less long game and iron spin with the same short game spin compared to the Pro V1x.\
