Dan, thanks for the link.
I believe Scott Witter is incorrect about the bunkering at CCB. I too thought the renovation was inaccurate for Ross's style of bunkering, but old photos in the halfway house show the bunkering much like it is now. As many know, Ross's bunkering was not the same at every course, and this seems to be the case at Country Club of Buffalo.
In order, my upstate Ross courses (of the ones I've played) would go:
Oak Hill (East) (just awesome despite some loss of Ross)
CC of Rochester (restoration/renovation puts new life into this one)
Oak Hill (West) (hidden gem that was ranked previously, best Ross greens anywhere notably 1-4, 6, 8, 11, 13, 14, 15, 17)
CC of Buffalo (quarry holes make this one totally unique, with a couple bland holes enhanced by heavy bunkering)
Teugega (a couple weak holes here and there with some unnecessary water features, but all of Ross is there)
Monroe (proposed restoration should make this one great)
Brook Lea (underrated gem with some great par threes)
Mark Twain (see above, but with fewer Ross bunkers)
This is in terms of overall course quality rather than faithfulness to Ross features. The most genuine Ross courses are, in order:
Teugega (lose the trees, bring back the sand in some of the grass bunkers and you've got the best course in Upstate NY)
CC of Buffalo (different from other Ross courses, but very genuine except for the pond on 17)
CC of Rochester (still has 5 non-Ross greens, but bunkering is very original)
Oak Hill (West) (lots of trees and lost bunkers, but 17 original greens make this one awesome)
Monroe (15 original greens, but bunkers are still shaggy and too many pine trees)
Brook Lea (great sets of greens and short holes, but some bland holes and a couple ponds bring this down a bit).
Oak Hill (East) (routing and greens mostly intact except for Fazio holes, creating the genius of most of the course)
Mark Twain (many lost bunkers + a non-original water feature, but great for a muny)
