I'd play Pebble Beach, just because...
Was never much of a fan of TPC Sawgrass, outside of the usual Sunday excitement on the 17th hole during the tournament. Doral never really appealed to me before the redo, and appealed even less after. Whistling Straits looks to be interesting, but not sure I'd spend 400 bucks to play there even if money were no object.
And although I've never played any of the Pinehurst courses, I know about a dozen guys who have and nearly all of them say #2 is way overrated and not overly enjoyable because the greens are so whacked out. A couple guys at my club went down there during the fall and played #6 (I think) and said it was a lot more fun and in great shape when they were down there, certainly more memorable anyway.
Ocean Course @ Kiawah Island - no thanks. If it can make a tour player look like a weekend hack, I don't imagine I'd make enough pars to stay remotely interested.
Spyglass Hill... yeah, I'd play there. Back in the day it used to be part of the Pro-Am rotation, I think??? Memory escapes me, but I seem to recall it being one of the courses at one time many years ago.
