Ian:
Did they change 15 and 16 as part of the change to 14, or did they just alter that approach? It doesn't look very much different to me, but it's hard to tell from a couple of pictures.
The change on #4 is more significant, but I'm not sure if I like it or not. You can't bounce a shot into the right half of the green because of the slope ... to bounce one in at all you used to have to play just inside the left bunker. Now, you'd have to play AROUND the new bunker if you are not going to fly it in [if they maintain that ground as fairway and not rough].
