Gary Denver, CO 105 mph Titleist Pro V1x I played in the USGA Senior Am qualifier in 2017 in Colorado Springs with Mark ____, a Snell rep who was playing it that day. We talked about it and he gave me a sleeve to try. I don't recall which model. I didn't play the ball again until after the MGS report came out. Ordered 5 dozen of the MTB-X (3 white and 2 yellow) and have played the ball since I got them.
