Aren't #'s 15 and 16 at Machrihanish both par 3's? Pretty good, as I recall - erspecially #16.
Have to vote for #15 at Cypress as a darn good hole with or without the setting. In fact, even with no wind it's a fine test. It's certainly much better than #7 at Pebble on a calm day IMO.
Isn't the beauty and setting of a hole part and parcel with its "greatness"?? I'll bet an exact replica of the "shot values" of Cypress #16 (length, elevation change, green size/contours, etc.) in a landlocked manmade setting without the visual effect of the ocean would be, at the least, underwhelming.
