The seventh generation of the three-piece Pro V1 has a slightly lower compression and a softer core than the last version. These changes, Titleist says, will help lower the ball's spin off the tee and increase distance. With the driver and long irons, the Pro V1 comes down on a shallower angle, which should provide a few more yards of roll. The four-piece Pro V1x is also longer, but this sixth-generation ball spins more with the long irons. According to the company, a new paint treatment keeps the ball white longer, and its uniform application makes for more consistency.

Titleist has officially released the latest versions of the most popular golf balls on the PGA Tour, the Pro V1 and Pro V1x.
Bill Morgan, senior vice president of golf ball research and development at Titleist, says, "This is the softest feeling Pro V1 we have ever made."
The three-piece Pro V1 has a large, solid core under an ionomer casing layer and a 352-dimple urethane cover. According to Morgan, the core material is fundamentally the same, but subtle tweaks have helped Titleist lower its compression and make the ball feel softer. He says doing that makes the ball spin slightly less than the last version.
According to Morgan, golfers will notice the slightly-reduced spin most when hitting long irons, but not as much when hitting drivers.
"Doing that means we've lowered the flight off the driver a little bit," Morgan says. "It's a little flatter, controlled flight."
He also notes that because the ball does not fly as high, it comes down on a slightly lower angle that should create more roll in the fairway. Morgan says that amateur players can expect to gain about 5 yards with the new Pro V1.
Around the green and on approach shots, the cast urethane cover is designed to help create more spin and control.
Adam Scott won the 2012 Australian Open in November while using a prototype version of the 2013 Pro V1.
The four-piece Pro V1x features an inner and outer core under an ionomer casing layer and 328-dimple cast urethane cover. It's designed for golfers who want even less spin off the tee than the Pro V1, but the inner core material, according to Morgan, is even softer than the core of the three-piece Pro V1.
Off the tee, this version of the Pro V1x should spin less than its predecessor and fly slightly lower, which will result in more roll in the fairway. With long irons, however, as a result of the modifications to the core, the ball should spin slightly more, according to Morgan.
Titleist also says that because of improvements in processing, the uniformity of the center and the positioning of the Pro V1x's inner core have been made more consistent than ever before.
"You know, any time you can reduce variation in your product and improve performance, that's something that the golfer can benefit from," says Morgan.
In the same week that Scott won with the new version of the Pro V1, Luke Donald used a prototype version of the 2013 Pro V1x to win the Dunlop Phoenix in Japan. Bubba Watson, Rickie Fowler, Webb Simpson and Zach Johnson have also switched to the 2013 version of the Pro V1x.
Titleist has added a sun-blocking material into the cover of both the Pro V1 and the Pro V1x to keep the white color from fading or browning if the cover gets scuffed or scratched.
The company also says that a new process that applies paint more thinly and uniformly, without sacrificing durability, has enhanced the aerodynamics of the dimples.
The 2013 Pro V1 and Pro V1x both have a suggested retail price of $62 per dozen.
