This is a good example of where I like to talk about “original design intent” and what is or is not “restoration”? As you know when Flynn built those greens there wasn’t bent grass in front of them rolling at 8 on the stimp meter where the balls would roll 50 yards back down the hill. The balls back then stopped much closer to the green and there probably were less “divot fields” so the design intent has definitely changed. I’m sure Flynn would not be happy with balls rolling 40 or 50 yards off the green into a small circle full of divots! This is what I would alter if I were ”restoring the design”. I would slightly modify many of those approaches given the new low cut grasses used today. Then you wouldn’t have to defend what Flynn did there and they still would present the challenge and interest he intended these false fronts to create.
