Titleist Test Balls

I received some Titleist  yellow test balls and have been playing them for about 2 months now and was very honored to be a part of this testing, i play at Kokopelli GC in Mesa, AZ and have been a very loyal Titkeist player, I liked the way the ball flight off the tee was and very easy to keep track of with the brighter yellow colour. I felt that they did well on my short game and putting the ball on very fast greens. I will continue to use the NXT and Pro V1. Thank you Titliest for allowing me to participate.

Hi. How did you become eligible to receive test balls etc. Thanks. Sal
