I was going to say the 18th at Pacific Dunes. Some really masterful work there. Not only does that bunker tie-in so well with the bunkering the back on the hill, in addition to what my eyes saw is another two or three bunkers right of the greenside one!
Bandon Dunes #14 is another great hole where I felt from the tee, the line of the hole went past the dune on the other side, only the hole turns right to the green playing in front of the dune, and the line of the bunkering there should have tipped me off, but it didn't! Not a single hole like it on the rest of the course, and that was refreshing!
Like Jeff Mingay, I think much of the charm of the Old Course is in its deception, and my favorite decpetion there is without doubt the second shot into Hole o' the Cross-In #13 where if your not careful you literally are aimed at the wrong pin of the biggest green in the world!
At Friars Head, I think the biggest deception for me is not paying attention to the lay of the land and how holes tend to follow it so much that you literally line yourself up directly at certain bunkers placed thorughout the course. My meaning is that if you do realize where your at in relation to the shot on any fo the par 5's going in or out of the dunes, its going to be a long, FUN day!
All of the places mentioned are like a roller-coaster ride for me!
