Since the USGA has limited the information that can be used for green reading as the ability of golfers to read greens using their own judgment is an essential skill that should be maintained should the same principal be applied to gauging yardages? Should there be no use of DMEs, very limited info in yardage books if they can even be used at all, no distances on sprinkler heads and maybe just go back to 150/200 yard markers, stakes or small bushes placed on either side of the fairway like in the "old days"? Should both the ability to read greens and the ability to gauge distances both be considered "essential skills"? If so why and if not why. Interested in opinions.
