Was the category supposed to be SHORT par-4 opening holes, or DRIVEABLE par-4 opening holes?
I'm a big fan of the former. I used to think Dan Jenkins was wrong to put the first at Merion (East) on his list of America's best 18 holes, because it's tough to hit two such precise shots right out of the box. But a short par-4 with a little leeway off the tee is a great start. The opener at Pacific Dunes doesn't have much leeway, so I would tend to favor the opening holes at Lost Dunes or The Rawls Course from my own courses. The first at Sebonack will be a shorty, too.
Some of the men's team at TTU think the first at The Rawls is driveable downwind. In general, though, I don't think you'll find many driveable par-4's being included as the openers on new courses. It is a speed of play issue, but aside from that, few architects or clients want the opening impression of their course to be "short" or "easy".
I was shocked to hear someone talking about the first at Riverdale Dunes being driveable; equipment [and altitude] must make a difference, because we never thought about that twenty years ago!
