Thank you for the opportunity to test out these prototype balls. Several people have stated the sound the ball makes of the drivers. I agree! I have never heard this type of sound before. What it resulted in was either a lower straighter trajectory or a higher fade trajectory. This was the first time I've hit a ball where my usual slice actually became a solid fade. The cover did take a couple strikes that would've ruined lesser balls. This one held up marvelously. The one major water hazard hole failed to fade away from the water. So I'm down to 2. They appear to go longer on my drives and stick on the greens when I wanted them to. Keep up the good work! Cant wait to play another round with my remaining balls.
