The two most intriguing holes to me were:
12 - Mostly due to the fact that its played to that fairway... at a diagonal, which must drive good players nuts. But it looks like a hole where you could experiment with strategy near endlessly.
15 - Not so much the landing zone for the drive which looks totally penal, but the approach into that green and surrounds just looks brilliant. All kinds of deception going on, and several ways to succeed or get in trouble. If any green and surrounds should become templatized from that course, my vote would be for this one.
P.S. Not sure what to make of 14. Just seemed odd that pros could eviscerate it with two iron shots, and its a par 5.
