The Titleist Pro V1 golf balls and Pro V1x Golf Balls are similar in construction. Despite their similarities, the V1x has less control than the V1 balls. Both balls are suitable for achieving distance and height, but the V1 flies slightly lower than the Vx. Both also reach large distances, but each utilizes a different specialized core. Unlike the V1, the V1x uses a four-piece center instead of a three-piece. This core makes it a little less stable and reaches a higher arc, while also allowing it to fall slightly faster than the V1 version. Additionally, they can both be used for long or short-distance plays, but if you want stability, reliability, and consistency, go with the Pro V1.
