Chip,
What a tough choice to think of a best green at Bandon. I love 5, 7, 8 at PD, 13, 17 at BD, and 5, 13, 17 at BT. I could probably name another half dozen on each course...
The setting on 13 is really cool. What strikes me is how gentle and wide the approach is, and yet it strikes fear into a mid-iron approach. So often today greens have a couple bunkers in the front that challenge you to make an aerial approach, but the back of the green is pretty easy. The width on the hole is also great in combination with the design of the green. You've got a TON of room off the tee, but an approach from outside the middle is daunting. We only played this hole twice on the last trip, but I remember the strong movement in the green and remembrance of thankfulness that I did not visit the right side bunker. In the end the hole has a cape feel to it.
