Just to throw a spin into this, many of the older archies work where there were long, sometimes flat bottomed with grass mounded bunkers, either crossing a FW at an angle, or wrapping around or running the length of a green, were "segmented" in remodelling efforts over the years. Many were reworked in their base and drainag and made cuppy in the bottoms rather than flatish. Sometimes this was done for maintenance. Sometimes for aethetics. Oddly, some of the previously remodelled long bunkers that were subsequently segmented, are now being restored to long and flatish with grassy mounds.

Put me in the proportionality and scaling camp... site specific.
