Ward,
I suppose a hole that shares almost all features with the 15th at NBWL is the truest reproduction of a Redan hole, but I will say I prefer the bastardised version that allows you to watch your ball in motion after it lands (eg. 4th at NGLA).
There are blind holes where I love the mystery of what has happened to your ball after it landed (approach to 3 at Cinque Ports, the drive on 5 at NSWGC, the drive on 4 at Barnbougle Dunes etc), I just prefer to watch the fun on a Redan.
