So i was a lucky test ball recipient here a few weeks back. part of my testing for what I can only assume is a new ProV1 (since that is what I play) was a durability test. The ball on the left is the second of three balls I received and the ball on the right is the last ball in the sleeve. The ball on the left has four 18 hole rounds on it and aside from one cart path hit which you can see just above and left of the "T" in Titleist it held up pretty good. The round scores were 71, 77, 71, 74...the last round was also played on fairways at my club that were 50% top dressed as we are readying for punching. Good work Titleist and thanks!
