I recently hit my second hole in one. Both using prov1x balls. The first was witnessed only by my wife. Although I was happy that she was there to see it, I wished others would have been there to add a bit more credability.(my wife is extremely honest,but when telling the story I could see doubt in some people. I never expected to get another chance, but one year and one week later, on the same hole,with the same club,and pretty much the same pin placement I sent a prov1x right over the pin and spun it back about a foot into the cup. This time I had FIVE witnesses.(my wife unfortunately was not one of them) I've been playing prov1 balls for about three years now. I have occasionally tried callaway blacks and the new nike balls, but even at a 12 handicap I can feel the differance especially around the greens. I currently use callaway clubs but I'm going to test titleist irons this spring. i hope they are as great as the balls. If they are phil mickelson should watch out, because there could be a new lefty on the seen!!
