Tom,
With respect to the ORIGINAL Cape, you touched on an important point everybody seems to have glossed over. We both know #14 at NGLA featured a green surrounded on three sides by water - sticking out into the bay like a thumb. The direct route was straight at it, over an expanse of water - but for those who did not dare the carry (it was LONG), the closer your tee shot to the fairway on the left, the shorter the pitch to the putting surface.
But the definition got perverted over the years to mean any hole with a diagonal tee shot to a well guarded green. #5 at Mid Ocean is probably the closest relative to the original Cape, but the green is/was definitely not driveable across Mangrove Lake, that is for sure.
Pretty obvious as we have all seen the new incarnation copied, augmented, stolen or whatever dozens of times.
My thought is the closest approximation in the list of C.B./Raynor templates is #16 at Cypress Point. Shac and I have gone round and round (putting aside Phil Young) about the genesis of that hole, but Mackenzie's 2nd book seems to have settled the issue about Raynor, Marion Hollins - and who conjured up the idea.
Of course, you can make the argument #16 at Cypress is also a Biarritz hole, but my recollection (only saw a painting of it, since it NLE in France) is the original Chasm Hole did not have a bailout area - so it was a longer, do or die version of your mentor's 17th at TPC Sawgrass.
That is the trouble with trying to pin a specific template label on ANY hole that is not a 100% copy - there are bound to be different ingredients added from the designer's bag of tricks. There are really only 12 notes in music - but Mozart and Jerry Garcia used them in significantly different ways.
Yes, there have been many attempts to write popular music with esoteric (read: bizarre) time signatures, but you are right, most of the time the results are idiotic like the Mermaid hole - or modifications of a perfectly composed piece of music that ends up more nonsensical than the current 12th tee at NGLA.
I've been trying to conjure up a first cousin to your 6th at Pacific Dunes, but think the only similar hole from the standpoint of strategic arrangements might be a modified Leven hole. Call it a 2nd cousin, twice removed . . . . but I suspect you used some similar notes to bake that cake.
You've heard my plaintive whining before, but if there is anything in golf resembling #7 at Pac Dunes or #10 at Apache, please point it out. And while you are at it, teach me how a reasonably skilled golfer might avoid making (yet another) double-bogey next time.
Don't be insulted, but a steady diet of either as a "template" might drive me to take up tennis.
