TomD and JimU, Thanks for the comments and explanations.

From my perspective OM works because these guys weren't trying to closely emulate holes at NGLA or abroad, but rather were willing and able to find the underlying strategic concepts in the existing features at OM. As Jim described above, some of these these features may have been augmented and altered as necessary --not in blind adherence to the "models" but rather to make the holes more interesting, playable, and fun. And I for one am glad they weren't forcing out of place features into the holes. OM is no place for a burn to nowhere.
I am sure some disagree, but I view their approach as similar to that of CBM at NGLA, and what CBM meant in 1906 when he said he would introduce the underlying principles "according to the nature of the land." Otherwise how could CBM have been inspired to build NGLA's 17th by a hole at Leven reportedly playing only 240 yards with burn splitting the hole at a bias and the green tucked left behind sharp hillocks? My view obviously differs from the views of some who expected more direct physical similarities, but to me this process of finding the fundamental concepts in the land whereever possible ought to be considered one of CBM's/NGLA's greatest legacies. In this regard, OM is a truer tribute to CBM/NGLA than it would have been had the designers tried to more closely adhere to the namesakes. This is the point I tried but failed to make above.
I've posted this before, but the topic of how closely a golf hole matches (or should match) its inspiration always reminds me of this quote from great British golf writer Henry Leach in 1920:
The sum total of the charms and virtues of a golfing hole in its own natural surroundings depends on many things, some of them quite indefinable, which no art can transplant nor imitate. I believe that a wise architect, however closely, in fact, he may try to model one of his creations upon some famous hole elsewhere, will hold his peace about it. If he confesses, those who do not know the famous original will call him sycophantic, those who do know it will deem him profane. If he keep silence, his plagiarism will most likely never be guessed at, and his brilliant and novel design will be warmly commended on all hands.
While these designers did not "keep silence" about their inspirations, I think that Bryan, Bill, and I all agree that they nonetheless deserve commendation for creating "brilliant and novel design."
