Interesting observation, David.
I am not sure if there is another course in the rota with as many doglegs, but i must admit that i like them a lot. They force players to think about their strategy and line of play. You can't simply bomb it as far as you can like you would on a straightaway hole. It's a sort of equalizer between bombers and shorter hitters. I mean, even if you're long and can carry those corners, you still risk finding big trouble if the ball doesn't quite make it, or if it rolls across the fairway.
Another advantage is the fact that a course with that many doglegs does not need to be 7600 yards to be interesting. It gives me hope that shorter clubs can still be hosts to tournaments and still provide great play without being to tricked up.
The routing, here, is in fact, quite interesting and varied with regards to wind direction. But I think in this case, the doglegs are probably the results of following what the land gave to the architects, and not something that was forced in for variety's sake. You can still make a great routing going in every direction without once having to use a dogleg....
