Have now tried the new Pro V1X 2017 balls. My feelings are that I hit them 5 to 10 yards longer and more consistent ball flight. I had these sent to me to try by Titleist late last fall. Being in Ontario Canada I waited until weather was warmer ( June 29017 ) before trying. Would use these on warmer days but use NXT Tour on colder days.
Keep up the good work Titleist.
