I switched to Pro V1s around three months ago after receiving a free box of them at an LPGA Amateurs event. Since that time, my GHIN has dropped 5 points AND recorded my first ever HIO!!! I'm convinced Titleist balls have made a huge difference in my game, and I will never forget the out of body experience of watching the ball go in for a Hole in One!!! Having my husband, BFF golf friend and her husband as witnesses made it that much more special.
