Ally,
I agree with your assessment. I actually prefer the Fishers Island Biarritz, because just as you stated, the approach shot is coming in at a lower angle which allows a player to run the ball after it lands, if that's what they choose to do. I should also mention the approach on the front of Fishers Island Biarritz is shorter than most greens you will find on muny courses.
Mike,
Fishers Island is certainly a Biarritz. Most Biarritz were designed with the front panel as approach and the rear plateau as green. Fishers Island has stayed true to their original design better than most Raynor courses out there. I personally prefer the original design to the 80 yard green variety because it allows for more recovery options for the player and it matches the designers intent.
I think another misconception we have with the Biarritz is that regardless of location and elevation we expect every Biarritz to play the same. There is a 1913 article introducing the Biarritz at Piping Rock. In that article, Devereux Emmet tells us how to play the Piping Rock Biarritz by running the ball on the front portion and running it through the swale. He didn't tell us how to play every Biarritz after that, just Piping Rocks.
If you look at Banks' description on how to play Yale's Biarritz he doesn't say anything about a low running shot. He suggests you hit a full shot to near the edge of the trench. The ideal shot at Yale is harder than most Biarritz because you have to land on the edge or in the downslope of the trench to get it to kick through the swale. The downslope on Yales Biarritz is close to twenty feet long, so it is possible, it's just hard! Now a days, many players can just as easily carry it to the back plateau, so it has lost some of its interest in that regard.
