I have noticed that MacKenzie normally, but not always, routed perpendicular to the contours, starting high, hitting to a low and back up to the green (Augusta, Crystal Downs). Dye routes more with the contours, with lows between tee landing and green areas. As green slopes have gotten softer, it becomes more difficult to see the green surface when using MacKenzie's philosophy, as the golfer is below the green and looking up, explaining many of the blind views to the green surfaces at Augusta. Always many exceptions and possibilities to this generalization. Strategic views to portions of greens depending on which side of the fairway always add interest and variety.
