Update: received my black number test balls on the 6th and have now played two rounds on my first test ball. I regularly play Pro V1's and am a 3 handicap index. Round one was a 72 (par 71) at my home course, an old school Country Club with tight fairways and postage stamp fast undulating greens. Ball was very workable off the tee for me and seemed to be 1/2 club or so longer. Impressed with ball flight as well. Round two was a 75 at a tough public course the next day (Par 72). I like the way the ball rolls and its performance around the greens as well. I was able to let the driver go a little more on this course and it performed well. I play all Titleist gear...913 D3, 913 Fd 5 wood, 712U 2 iron, 714MB 4-5 iron, 712 MB 6-PW, Vokey SM5 Black Oxide 60, 56, 52 wedges  (all irons 6.5 project X 1" over)  Cameron Newport 2.5. So far the ball after two rounds hardly looks played. I think its a winner.
