Titleist has Tour only Pro Vs

If you have any of them in your golf bag, you’ll be able to tell by the markings on the side of the ball. The Plus Spin is marked with on the seam while the Plus Trajectory has <+---PRO V1x---> on its seam.

A Titleist rep said, "These products are customized versions of 2009 Pro V1 and Pro V1x golf balls that have been designed to optimize performance for a small handful of PGA Tour players."

Having said that, only six players in the entire field were using the ball... It will not be sold commercially. It’s all about having friends in the right places with this one...
