Doug,
I know all that. I don't care what the sign says or how abundantly clear the notion is. Frankly, the clearer the notion, the less I like such a course. Pine Valley was designed to be a course for the best players yet it has an abundance of qualities that cannot be found at Bethpage Black. It has variety of hole lengths, shot demands, topography, green slopes and contours, bunkering, etc. that provides a unique character and feel that is welcoming. Pine Valley has wide LZs and can be played by a wider range of players than Bethpage's Black course. Bethpage Black is one dimensional and not very interesting. It lacks something. I think it is both character and charm.
A golf course that is challenging for the best players can still have charm, nuance, deception, long and short holes and a variety of shot demands. It is a better design if it possesses such qualities. The one dimensional design of Bethpage Black and the overdose of big bunkers with the goofy and repetitive capes and bays that spoils the view and playability of the engaging topography. This a failure in my mind and would therefore not qualify for my "best" consideration. Best is completely subjective and by my criteria it fails utterly. The fact that a sign says it is not for everyone does not give it a free pass in a subjective or objective analysis.
