In case anyone can't read what comes later, I don't feel that caddies are VITAL to any shot at the Bandon Resort, but here are two where they could be particularly helpful the first time one encounters these particular scenarios...
#5 Pacific Dunes--in many, many instances the proper play to all front and many middle hole locations is to bounce/feed a shot off the fairway and/or mounds short left of the green
#8 Pacific Dunes--hole locations to the middle right and most of the back of the green are just begging to be accessed by playing off the hill to the right of the green, rather than on the direct route...
once a player has encountered these, subsequent playings of those two situations should be self-evident...
These are just two very specific scenarios off the top of my head...
Again, caddy not VITAL to either, but those playing lines could increase the enjoyment potential...
