Tom,
With the exception of Carnoustie, I have never played a truly great links course that was not fairly easy in a slack wind.
Part of the charm of Pac Dunes is that you have to run the ball into so many of the greens - a skill made far more difficult in a substantial breeze.
The problem in this case lies in the inability of some of the raters to visualize the playing characteristics of the golf course under a variety of conditions.
Personally, I have played the golf course four times (once with you). In benign conditions, the golf course is a joy - a relaxing tour through a string of naturalistic landforms introducing all sorts of creative options.
In a blazing gale, Pac Dunes is almost too hard. I remember taking a 13 on the 13th hole without hitting a really bad shot . . . . . ironically, while playing with a GD employee named "Lucky."
You showed me some of those "alternate tees" hidden around the golf course. If hard is what they want, send them out there in a four-club wind from the Kaiser Tees and all those "hard-is-good" machomen will need a neck tourniquet to stop the bleeding from their ears.
In slack conditions, the only change I might make is to jazz up the 8th fairway with some bunkering, and maybe put in some kind of penalty for missing the par-3 14th short and left.
Besides that, there are not many things I would change.
One question though: I have always been a bit confused by the lack of room between "Shoe's" Bunker (the center pot) and the left edge of the fairway off the tee.
Hitting into that alley, the approach is clear and open to the green. From the Papazian Chicken-out side (the right), the approach is blind, over bunkers and dunes, and from an uneven lie. Oh, and also against the wind.
If the tee was centered a bit more instead of being located on the right side, it would be tempting for shorter hitters. As it plays, it seems the only shot to get a clear approach is a long blast over Shoe's sandpit. It would be far more interesting if there was an option for low-ball hitters to sneak a runner into the gap to leave a clear shot.
Ever think of putting in another tee?
