I don't care too much for the downhill versions, the others are more attractive to me so long as the green falls away behind the bunker.
I think it's because I like to be surprised by where the ball winds up.
Whatever the topography, it has to be firm to play properly.
I have played NGLA, The Creek, Yale, Mid-Ocean, and Mountain Lake, but prefer the original at North Berwick.
I've also played Tom Doak's modern evocations at Pacific Dunes and Apache Stronghold, but they lack fall away slope to the degree essential for the very best Redans.
