I see no reason *not* to start with a par-3, just as I do not object to finishing with one either (Pasatiempo).
A reasonable par-5 probably works best to sort out the 1st tee kinks - but my prejudice towards that opener might be rooted in what I grew up playing.
O-Club Lake, Ocean, SFGC, Cal Club, Harding, Half Moon Bay Old, Poplar Creek & Meadow Club all start out with a gentle par-5 handshake. After that, there are plenty of Donald Ross "real nuts to crack" waiting patiently down the line.
The fact #1 on the Lake got played as a par-4 last Open is irrelevant - artificial USGA perversions don't count.
The one thing I *do not* like is for the horsewhip to come out right off the bat - like at Oakmont. Loooong par-4, followed by 3-iron to a green (sloping away) is a bit much for the first bite of a shit sandwich.
Actually Henry Fownes must have been a self-flagellating Calvinist, because going off on #10 buys you nearly the same kick in the groin.
If I'm going to subject myself to the gauntlet, blow-torch to the face as an opening gambit was too much for the 2 handicap version of me . . . . At this point, fergetaboutit!
If I lived in Pittsburgh, my 50th birthday present to myself would have been resigning from Oakmont and joining Fox Chapel.
I long ago reached a point when having fun trumps "being challenged" - because the older I get, the longer and harder the courses become . . . . . standing on the 2nd tee, feeling discouraged and defeated with a double-bogey on the card, takes the gas out of my already flaccid balloon.
I've gotta say though, #1 at PV never struck me as a terribly difficult opener. The landing area is wide enough to land a 747 and the fairway segues seamlessly into an enormous putting surface.
Once you get a look at the pits of perdition on either side it might pucker your rectum a bit on a return visit, but compared to #1 at Oakmont or WF West - well, there is no comparison.
Give me a little daylight off the first tee . . . . . please.
