Long rough is not trouble? Having to chip out of long rough from behind a green into a green that slopes back to front will most certainly cost all but highly skilled golfers at a least a stroke. While bunkers in front of greens may be more common, it seems to me that there is most always an area of fairway open to the green in front. Leaving a ball just short of a green on the short grass leaves easier up and down possibilities than chipping from behind the green in most cases. At least where I play. Just short of a green in the short grass=Better chance at up and down par. Kevin
