Mark,
As of the late 1980's, when my father (who at the time was a greens chairman of a Ross design), went down to play Woodhill in an effort to gain some additional knowledge of Ross' work. He was directly there because the original design was intact, except for 2 Cornish bunkers that had been added and were clearly different in character from the others. Judging from the pictures, the terrain has some nice, natural golf contours, nothing too severe, but enough to add plenty of interest to the game.
