Let me suggest that the modern interpretation of the Redan is better, that it offers more compelling options for the player.
I live in Oregon, and have played both Bandon Redans enough to have an opinion. I've played the 17th at Pacific Dunes 25 times or so. For most of the last 15 years, I've played a draw, or at least have been able to play a draw reliably. Most times on this hole I played the low draw, even into the quartering wind. The 17th is one of thoe holes that offers great ball watching from the tee. If you can hit your spot, the ball will take its sweet time getting to the left side of the green, but it'll get there.
For the last three or four years, I've lost the reliable draw, and tend to hit the ball straight. A straight shot at the front of the green still works. Sometimes, I'll be feeling sporty, and try to fade a 7-wood into the slope, and have succeeded at least once. Very satisfying.
Similarly, I have played the 12th at Old Macdonald several times. I've hit the green twice in seven attempts. From the middle tees one day, I bounced a low 5-iron up the slope to a short pin perfectly, and felt like a king for 12 minutes. Another day I tried the faded 4-wood from the back tees to a middle pin and made an easy two putt par.
Just because you couldn't fly it onto the Redan in 1925 doesn't mean it was better then.
Tom, the 12th at Old Macdonald does not appear to have the high right kick slope previously described in this thread. Does it?
