I am seventy years old, I 've been playing golf for 60 years, I feel like i am in great shape because of golf and the exercise it provides. Had a hole in one yesterday at oak valley CC near clemmons nc. Its my 7th. earlier in the round i made a 97 yard shot from the fairway on no 5. on no 16 i made a 1 also from 97 yards. As with most of my aces, the ball sucked in from behind the hole. I have played Titleist golf balls for all 60 years. I would not tee up any other brand. Pro v 1 is the best.
