D Moriarty,
I mean greens that are the same level as the fairway, obviously mown shorter, but not below or above the fairway, or banks, crowns or plateaux. Something were it would be a fine question of judgement as to where exactly you wanted to land your shot, because you could never be sure whether the point you were aiming was green, or thirty yards short.
I guess grass type depends upon climatic conditions and usage, and i doubt whether they would work well if the fairway before and after was flat.
