AKay, et al:
Oak Hill / East needs to buzzsaw plenty of the timber that engulfs the course. In real terms -- Oak Hill / East is the east coast equivalent of Olympic / Lake -- it's time for the lumber to be cut so that the playing angles of the course can be brought back into play.
What you have is a difficult but limited strategic course IMHO.
How GD rates it among the nationa's ten best is a major league stretch in my mind. Oak Hill has benefited from being able to host a number of prestigious events (e.g. US Open, PGA, Ryder Cup, etc, etc) and that visibility has translated into the kind of "bump up" in assessments by many people.
It doesn't hurt that Donald Ross is associated with the layout but truth be told I really enjoyed the sister course for what it is. When the Tom & George Fazio duo changed the golf course one has to ask did the work really improve upon what was already there?
From a straightforward architectural assessment I think Oak Hill is just not in the same league with other New York State courses that finished behind it (e.g. Bethpage Black, Fisher's Island, Fenway, Olde Kinderhook, to name just four).
From my experience the holes at Oak Hill really aren't really unique, however, it simply produces a steady stream of relative sameness -- although I do enjoy the short uphill 14th hole -- most err towards difficulty in order to make up for what it lacks in terms of memorability.
I'll concede a top 100 position -- but a top ten position is almost as bad as St. Joseph's getting a #1 seed!
