With regards to the feeling that there's too much sameness coming from Mr. Doak's recent work (I haven't seen/played any of his more recent projects, so this is based on pictures):
I'd have to say that I agree that there are numerous similarities in the pictures I've seen, and there is no doubt in my mind that the holes are in fact very similar. Is this a bad thing? I say NO, because if such courses as Stone Eagle and BallyNeal emerge as classics, more people will want to play such imaginative holes. Of course, few will have that opportunity, given the private nature of these two clubs. But, if more, similar courses and holes start popping up, their merit will be realized by more of the golfing public. Isn't that what it's all about? We all want the lay-golfers to realize what great course design is, so isn't the emergence of more new-school, but perhaps similar courses the best way to accomplish this?
Chances are, I'll never play some courses on a level with Pine Valley, Augusta National, or Sand Hills. But if more similar (to these) courses emerged, I may have such an opportunity, albeit on a lower level. And that's beter than not experiencing anything like it.
