Just used up my last ball from my sleeve of new "test" balls. They were awesome, pretty sure they were the new version of the ProV1 due to its performance. I felt that I could get the ball to spin more than the previous model. I also saw more durability in the ball, I was able to play one ball for multiple rounds and it withstood all my wedges and irons. Better than the old ProV1 in my mind. The only downfall is that I felt it was just a little softer so I lost a few yards in distance. But for the most part I would give it a solid A- as a whjole ball.
