TEPaul,
I think, out of sheer luck, that you identified the principle reason that many flanking and surrounding bunkers were eliminated or divided, THE CART AND THE ANGLE OF APPROACH AND EXIT.
David Moriarty,
With respect to plasticine models, we shouldn't assume that the plasticine model is representative of what was put into the ground.
The 12th at NGLA is a perfect example.
I think it's also incorrect to take Whigham literally in the context that the concept of a Biarritz, or any template, didn't evolve or morph over time.
In my limited experience of examining templates, there's no "static" or fixed master mold, where the features are congruent.
Similar in general terms ? Yes, but, with enough deviation that the hole is unique in its own right..
A great number of "templates" vary greatly, yet they still maintain their general concept.
I've always been fascinated by the 6th green at Piping Rock and the 17th green at Westhampton.
Especially the treatment at the back section of the green.
