I've struggled with the yips all year and I didn't 3 putt a single green on the Black.
I also birdied 2, 5, 17, and just missed a few others by a hair. Played well and shot 77.
I have to wonder if The Old Course was opened in 2017 if we wouldn't be bitching about the huge, over the top greens, particularly on a windy site?
I found the Black to be a wide open playground. Figure out how to make a score, no?
As far as Tom's original.question I always preferred the Blue over Red because I appreciate the pacing and variety of holes, the non-obviousness of the strategies, and the intersections and interjections of bunkers at critical places. In contrast it seemed many of the easier holes on Red are grouped together early and the hard, long ones get a bit relentless on the back nine of the Red.
Without going into much more detail on the Black at the moment I'd say it likely won't photograph particularly well in the same way TOC doesn't. There just isn't the visual drama that some love except perhaps on the three finishing holes.
10 rounds I'd go 4 Blue, 4 Black, 2 Red.
