The short answer: most of you should not switch just because a playing partner did. I compared the Pro V1 and Pro V1x the way a golfer actually buys a dozen — swing speed, flight, and whether the greenside spin is worth the extra spin off the driver.
This is one of the most common golf equipment questions — and one of the most misunderstood. The Pro V1 and Pro V1x are both elite tour balls from the same manufacturer, made with similar materials and construction. The differences are real but subtle, and getting them wrong for your swing can actually hurt your game more than help it.
Titleist Pro V1
The Pro V1 is a three-piece urethane ball with a softer compression (approximately 87). It produces a mid-high, penetrating ball flight with a soft feel at impact and high greenside spin. The trajectory tends to run a bit lower and the ball spins slightly more on short game shots than the V1x, making it the preferred choice for players who want maximum short game control and a slightly softer feel throughout the bag.
Tour professionals who prefer a softer feel, slightly lower ball flight, and maximum greenside responsiveness tend to play the Pro V1. It rewards players who use spin as a scoring tool rather than pure speed.
Price: ~$54/dozen
Titleist Pro V1x
The Pro V1x is a four-piece urethane ball with a firmer compression (approximately 100). It launches higher and spins less off the driver — specifically useful for faster swingers who generate too much spin and balloon the ball on driver shots. The firmer feel is noticeable at impact across all clubs, and the higher trajectory can be an advantage when you need to hold firm greens from distance.
The Pro V1x suits players with faster swing speeds (above 100 mph driver) who want to reduce driver spin, or players who prefer a higher ball flight and firmer feel throughout.
Price: ~$54/dozen
Head to Head
Driver spin: Pro V1x spins less off the driver — meaningful for faster swingers who balloon the ball.
Ball flight: Pro V1x launches higher. Pro V1 is more penetrating.
Feel: Pro V1 is noticeably softer. Pro V1x is firmer throughout the bag.
Greenside spin: Pro V1 generates slightly more greenside spin for maximum short game control.
Price: Identical at ~$54/dozen.
Best for: Pro V1 for players under 100 mph driver speed, those who prefer soft feel, or players whose priority is maximizing greenside spin. Pro V1x for players above 100 mph who spin the driver too much, prefer a higher ball flight, or want a firmer feel throughout.
The Bottom Line
The easiest rule of thumb: if you spin the driver too much and the ball balloons, try the V1x. If you want the softest feel and maximum short game spin, stay with the V1. When in doubt, buy a sleeve of each and pay attention to driver trajectory and putting feel — those two data points will tell you everything you need to know.
