I had completely changed my grip and swing and this was the first time out since implementing the changes. I was so busy concentrating on the mechanics that I didn't look up at the ball until it hit the green. It checked up once and rolled toward the hole. It wasn't until a friend rode up to the hole (on a Golfboard) that we all realized what happened. 168 yards with a 7 iron and Pro V1. First hole in one after 11 years playing. I want another one!
