I don't understand why there is debate over closely mown areas. Here is why:
I have seen 12 different links courses on my trip, and (most of them) are quite old. They all use closely mown areas. Now, you might say that because they are links courses, you have to compare them differently to the vast majority of non-links courses. Links courses....
1. Are firm and fast
2. Have the wind as a cooperative factor
So, why do links courses have closely mown areas? Is it to help players with the two factors above? More room for the bounces and rolls of firm and fast turf and the push/pull of the wind? Sure that is part of it, but if there is one thing I have learned on the trip, it is how closely mown areas enhance the green surrounds. It makes the depressions and bunkers play larger and more difficult, but can also make the green play larger with slopes feeding the ball in and the short cut of the grass itself. Closely mown surrounds are an integral link between green and the fairway.
Also, these courses are the root of the game. They came first.
So this leaves me asking two styles of questions as to why closely mown areas aren't used more....
1) When did closely mown areas "fall out of style?" Why is it a problem that they are "coming back in style?"
2) Why have rough when you can add style, complexity, and creativity (shotmaking from green-side, shotmaking into the green, and for the architect sculpting) with closely mown areas?
