I think the greatest applications of the great hazard concept are when the hazard is not just large but angled. Bethpage #4, Baltusrol #17 are some of Tillinghast's greats amongst others. I think Streamsong Blue #17 is also in this class (however into the wind #18 is much harder). I feel that Pine Valley #7 is a different beast, as it is a large block hazard, not angled. The example at Dormie #17 may be too extreme with the uphill shot, the sand part of the hazard may be a benefit, as opposed to tall grass. Overall, the concept is fabulous.
