I just tested the 2019 Proto golf ball that Titleist sent me in the mail. Played on my home course so I was accustomed to distances I typically hit. It was very long off the driver. Off the irons, the ball flight similar to ProVI. Soft around the greens. Don't know much about what it will be branded under but when I find out, I will switch immediately. The Proto was definitely better for my game. Incidentally, my handicap is 3, my irons are Titleist T-MB, 3 Wood and Hybrid are Titleist. Only club in the back not Titleist is my driver.
