Jonathan and Tim,
I'm a little surprised that neither of you liked True Blue, though that love-hate reaction seems to be the nature of Strantz courses. I liked TB a lot less than Caledonia, for instance, the first time I played them, but TB has grown in my estimation each return trip. I liked Tot Hill as well, but nowhere close to TB.
I agree with Paul Cowley that the observation that Stantz did better work on smaller sites is interesting. TB, however, doesn't fit that in my mind. More than any other course that I have ever played, TB MUST be played from the correct tees, and I don't believe that those are going to be the tips for almost any golfers. At about 6500 yds. (which is roughly the same yardage as Caledonia) TB is a blast. At yardages longer than that, TB just isn't much fun.
However, in the case of ANY Strantz course, I can't really imagine saying "skip it" to someone interested in GCA. They are just too beautiful, too compelling, and too unusual.
