Grant,
I don't believe your premise is correct, if anything, it's the reverse.
My experience playing Biarritz's dates to the mid-50's when I was playing the 13th at The Knoll and the 2nd at Essex County West on a regular basis.
The 13th at The Knoll played between 220 and 250 and most golfers in the mid-50's couldn't come close to carrying the ball 220 to 250, so the shot of choice was to try to either pure it to the front of the back level or try to hit the downslope of the first level or try to hit a low driver or 3-wood that would run the required distance no matter where it first hit the ground.
I'm not sure, and am trying to remember if the front portion of the 13th, which was NOT maintained as putting surface had a set of deflecting or correcting spines that would either redirect the ball toward the green or into the flanking bunkers, depending upon the flight of your ball.
None of the three above shots were easy, but I do recall that the most successful of the shots was the second alternative.
The 13th at the Knoll was elevated above the surrounding terrain, so a missed shot usually ended up in deep flanking bunkers.
The Knoll had two distinct features within the putting surface of two of it's template holes.
On it's Redan, it had a spine running through the green and on it's Biarritz it had a ridge/mound in the back section.
Both are very unusual features for those templates.
It was a very difficult par 3.
While scores higher than bogey weren't usually the case, pars were difficult and birdies almost unheard of.
It was the kind of hole you thought about earlier in the round if you had a good round going.
Today, I see mid to high handicap players capable of carrying to the back section of a Biarritz without much difficulty
Firm, dry fairway turf will produce far more roll than wet putting surfaces.
And in the mid-50's, at the Knoll in the summer, the fairways were firm unless Mother Nature decided otherwise.
I would imagine that the 9th at Piping Rock played the same way early in it's existence.
The depth of the gully may hold the key to playing Biarritz holes.
