Would the definition/nominations vary as to class of golfer?
Some seem to think tough rolling greens would make it the best 60 and in course. However, if I was a short hitter who depended on the short game to get me up and in from just in front of the green, my definition might be a flat area in that zone, plus long rolling green contours I could use to get my short pitch (or pitch and run) close to the hole with a creative shot.
Would you design the 60 and in for that kind of player, or for a good player who might never use that feature, since they never come up that short? Or, does 60 and in count laterally, too, for those guys who are pin high but have missed left and right?
