Patrick:
I sense that Ran is not necessarily referring to what might be viewed as "transition" holes; instead, he focuses on holes that perhaps don't have spectacular natural features, but have some degree of strategy and architectural merit, and don't compete visually -- and to some extent aren't as intensly strategic -- as the holes that everyone talks about after a round. (By intensly strategic, I'd think of something like the 3rd at NGLA recently posted in pictures here -- boy, that hole, and I've never played it, must make one think hard all the way from the tee to the cup.)
For me (since Ran asked), I'd think of the 9th at Lawsonia. At that course, holes 1-8 are just one visual and strategic feast after another, full of enormously pushed up greens, severe green contours, blind and semi-blind drives, strategy all over the place. The 9th is something of a respite -- a sweeping par 5 of @ 530 yards, gently uphill, with something of a blind second, but not the kind of typical blind Lawsonia shot that makes you nervous or plays into strategy. The green is one of the more benign at the course, both in terms of its relationship to the ground, and its contours. It's not a transitional hole (Lawsonia has others that fit that bill, in the sense that Patrick refers to), merely a way to conclude the front 9 in a way that's somewhat less dramatic than everything that proceeds it.
