The problem with the Biarritz template today (and probably the reason many don't like (or appreciate) the concept) is that the modern game has pretty much made obsolete the way in which CBM intended the hole to be played. As with all of his template concepts, you have to remember that he was trying to test a variety of shots over the course of a round, believing that the ideal course was going to demand well-rounded skill from the golfer.
Just as the Short hole demands a very precise lofted shot to a specific portion of the green, the Biarritz demanded a long running approach that would hold its line, and would be struck so that the run out would traverse the "hogsback" and feed to the green itself. These terms have all become a bit muddled, as Raynor and Banks later started grassing the front portion (the hogsback) as green, perhaps in an effort to enable the run out aspect of the shot.
Today, many players are flying their shots well past the hogsback, and when pinned in the front are even stopping their shots on that section. In this way, CBM's intent has been lost, as that manner of play has made the long running shot unnecessary. It is of interest to note that the player that doesn't have that long carry shot is staying true to the hole's intent when they are able to judge the bounce and run shot correctly.
It would be nice to think that the Biarritz template intent could be made relevant today if the length of those holes could be adjusted to modern distances. A 200 yard Biarritz in 1920 would probably need another 60 or 70 yards to make it relevant for today's better players, and the course would need to be maintained firm enough to allow for the roll.
In short, anytime you step up to a "Biarritz Style" hole, or a hole with a "Biarritz Style" green, and you are not trying to run the ball to the hole location, you are not playing a Biarritz as CBM intended it.
