I don't think you should try to put all these many "Redans" into groups of right or wrong or even to compare them to No Berwick 15.
This is just a magnificent golf strategy, to many - including myself, perhaps the best golf strategy whether it be on a par-3, 4 or occasionally on a par-5.
You usually cannot find the "proper" topography that matches 15-No Ber and, you know what? - who cares. There are various "less-than-true" Redan type holes that are very fine holes and fun to play.
There are a very few "elite" Redan holes - sort of the best of the best - and these should be truly revered as exceptional renditions of this genre and I'll leave it to you guys to discuss them - it's fun.
I think the various posts about this subject is really helpful, especially for the many who may not fully understand the Redan (or other) strategy. I would bet that many of those readers/posters have been playing Redans for years not knowing it. I'm sure there are a lot of guys who might be too intimidated by this sight to ask. So this is what we are here for - to enlighten one another. Fun stuff.
