Matt;
It looks to me like you've gotten the definition of a member's course down pretty comprehensively!
To me a good indiction of a good members course are those in the 6300-6800yd range but with good and interesting architecture, variety etc.
Real Championship courses are hardly ever good member's courses--the likes of Shinnecock, Oakmont, Pine Valley, Aronomink, Pinehurst #2, Rolling Green, Huntingdon Valley, Merion etc are not good members courses for a variety of reasons. Generally a course with a real high slope and/or a high rating (generally distance related) is not a good member's course.
Courses that might be considered good members courses but might have the capacity or ability to transition into something else because of wind or maybe a wide set-up spectrum would be the likes of Seminole, NGLA, Riviera, or even Maidstone, Fishers etc.
True members courses would the likes of Gulf Stream, Gulph Mills, Misquamicut, and a zillion other Ross courses, for instance!
