Putting with flagstick in or out?
Since the rule change it has been interesting watching how different players now putt. For me if I have a putt longer than 30 feet I have left it in. One reason is that so many players do not tend the flag properly and it is one less distraction. The second for a number of players is helping with depth perception and gives confidence.
I hope that whatever decision you make commit to the putt and make a good stroke.
