I have just recently switched to the new generation on ProV1xs and have notice strokes taken off of my game, which makes me very happy. At the beginning of the summer I was an 8 handicap, using the cally Chrome Soft that had come out in January. A friend of mine gave me a sleeve of the new Titleist ProV1xs and I shot 75 that round rather than the constant low 80s I shot all spring. After the round, I bought a dozen Prov1xs and managed to consistently shoot mid to high 70s and got my handicap down to a 6. I will continue to use Titleist golf balls until the end of my golf career and look forward to the Titleist improvements in the game.
