Tim,
To me, the 11th at The Creek is the ideal island green due to the enormous variety presented by the size and shape of the green along with the varying tee lengths, the water and the WIND.
The green is a modified Biarritz in that the swale is not as pronounced as Yale's and others, nonetheless, I've never seen greater variety in a par 3 hole.
The green is about 90 yards in depth, probably 40 or so yards wide.
Go to Google earth and look at it.
It's on the North Shore of Long Island, right on the LI Sound, in Locust Valley.
