I would humbly put the three finishing holes at Jack's Pawleys Plantation up against those of any American course at least.
16: 444 yard par 4, dogleg left, OB lurking on both sides off the tee, and a firm green exposed to wind and quarded by bunkers and marsh.
17: 205 yard par 4, all carry over marsh to a 15 yard deep green with OB lurking behind
18: 443 yard par 4, narrow landing area (marsh, bunker, trees), narrow green guarded by swales, sand, and water. I'll try to post pics when I have a chance.
