I've always been fond of the use of fescue roughs, especially in an unevenly integrated form (kinda clumpy looking, that sort of thing). However, the preference seems to have fescue as being overly thick such that a lost ball is more than commonplace.
What are some methods by which fescue can be maintained as a light and whispy variety that annoys the shot, but still allows it to take place? Is it costly?
