I was chosen to test the new AVX balls recently. I am 59 years old and a 15-16 handicap. I have a slower swing speed ( due to back and muscle issues). I played the ball last weekend and gained about 10 yards off the tee. Iron shots felt solid and trajectory was good. Wedge shots stopped on a dime! Around the green, some chips stopped too much. Putting (one of my weak areas) , the ball felt great. All around, to me, the ball is a winner. Thank you Titleist for the opportunity to help you with your research.
