I've been a member of Team Titleist for a couple of years, received two "Test" ball sleeves during that period and I just wanted to say thanks. It was a blast comparing them to the balls I ordinarily played at the time. Beyond that, I've playe Titleist NXT Tour S balls in optic yellow for the last 6 months and I have to say they are the best ball I've ever played. Soft on the putter face, medium spin and straight as an arrow off the tee. Keep up the good work and I hope Illinois gets to be one of the States picked for the Team Titleist Member Invitationals.
