Adrian,
Since my golfing experience is limited to the US (and about 20 courses in Australia and Ireland) I have never played any of your courses, but I would like to. It is nice to learn that others have copied you, because it means you built something worthy of imitation!
I imagine that any architect, (real or pretend,) has to make a choice early on if they will employ template features or not. It is natural that most do not, and this is a good thing since it expands the variety of golfing experiences for golfers. So I respect your answer to the original post: none.
Personally, if I were designing a course I would look for one green site that is perfectly suited for a Redan. I'd do that partially because I love playing Redans, but more importantly, because I could have confidence that even if I built 17 other crappy holes, the Redan would probably be a good golf hole.
