I currently carry 6 golf balls during my rounds. This is down 6 from previous years. In the past as I would find balls, if they were what I played(Pro V 1s) I would clean them up, mark it(3 Blue dots) and keep them in the bag. At different times I would have close to 18 balls in my carry bag…NOT SMART…Soooo this year I still clean & mark good finds, but keep anything over 6 balls in a small container in the back on the car. Much easier on my back!!!
