I was a ball tester for Titleist 3 years ago and went through 2 sleeves so I had a pretty good experience before losing them. I gushed in my reviews and reply on my results. It had the Pro V arrow but the ball was marked 'test'. I told them in the online survey that it performed like the NXT Tour only longer and with more spin on the green - could this be it? Shortly after completing the test, I found a couple of NXT Tour Ss and initially liked them, bought a dozen for a 4 day tournament, and didn't like the 'feel' - a little too firm so I don't think these were the ball I had been testing.
