I was given two sleeves of HP tour Titleist golf balls from my brother-in-law who no longer plays golf so I told him thank you and that I was going to make a hole-in-one with one of these balls. Remarkably the first time I used one of these balls I did make a hole in one on the very first par 3. I'm not sure how old these balls are but they proved to be The number one ball in golf for me ! This is my second hole in one using Titleist golf balls. I normally use the Pro V 1's! Thank you Titleist for this outstanding achievement !
