I have been lucky to play THE Redan a number of times. I think you should have a shorter list of redans.
I tend to agree. There are basic tenants of The Redan that when combined make the hole what it is.
1. Overall at least flat if not uphill to the front of the green. Green should at least be obscured and landing zone blind.
2. A dip shy of the green.
3. Trouble both sides of the green, but one side more favourable and one side with a steep fall away.
4. Space to the rear of green. This feature is tightly aligned with 5.
5. Tilted and front to back green.
It would be better if the original named holes stood alone as they generally are unique. However, if the names of these holes are to be used as a way to describe other holes they should fairly accurately reflect the attributes of the originals or have qualifiers to more accurately describe the hole. I recall seeing Yeamans Redan the first time and thinking, no, it's certainly not close in design to The Redan for that name to be an accurate description, but it's a very good hole. Merion's Redan is a bad joke.
