I have no idea if trees were removed, Sean. It wouldn't surprise me if Rees added length to the back tees when he redid the course a few years ago. If so, this would exacerbate Matthew's complaint about the green's diminutive scale with respect to the distance of the approach.
Matthew, it is a very tough target. I failed to find the surface with all 4 tries, 2 of which were briefly on the green (don't tell the marshall). As a set, I can think of few tougher short-hole collections.
