Tom,
You certainly jazzed up #3 with two centerline bunkers, and a well protected smallish green. Was it a case of already having too many notes by #12?
We built twelve holes at Pacific Dunes the first winter/spring; they were the holes closest to the clubhouse.
We had six more to complete the job: 3-4-12 and 13-14-15.
4 and 13 were already laying there, mostly, although the 4th green site is some of Jim Urbina's best work ever.
14 was a fair amount of work -- I had to borrow ski goggles for two days to get the green roughed in -- but the idea was clear-cut.
So the last three holes to decide what to do were 3, 12, and 15, which are three of the four par-5 holes. By then everyone understood how good a course we were working on, and there was a lot of pressure to make those three holes "stand up to" the rest, as Tillinghast famously said.
#3 had the beautiful view from the green site, so we just made it interesting strategically, and figured it was fine.
I thought the 15th could rest on its cool green site, but Mr. Keiser thought it needed more jazz between the tee and the green. I had always thought of it as similar to the 14th at Dornoch -- or at least, as similar as I will ever get to see -- and that hole has NO jazz other than the natural ridges between the tee and the green, so I was resistant to over-doing it, but Mike was strongly in favor. And I pretty much said okay, we will keep working on that one until you're happy, as long as we can keep #12 pretty simple. I figured it fell between the two most memorable holes on the course, and any attempt to jazz it up would just look silly.
In the end, I would say the 12th at Pacific is probably the least compelling hole on the course, but I would argue that is one of its strengths. The bunker in the fairway for the second shot is exactly in the right spot when it's into the wind, or when there is no wind. And in the summer, when the wind is in your face, it plays like the longest hole on the planet and it benefits from the lack of embellishment. I am very glad I argued for it, even though there are many geniuses who think it ought to have "more strategy", i.e. more bunkers. I doubt they would like their idea as much if they had to putt out with sand still in their teeth from playing out of another fairway bunker.
