I only got to play it once, in the pre-opening GCA round last Saturday, so it is hard to answer definitively. However, in my one round I noticed that most holes had a preferred side for the best attack, and that line made you deal with bunkers and occasionally, the gorse. There are definitely really wide safe routes and much more challenging lnes for low handicappers.
For example, on the Road Hole, I could have aimed left and never missed the fairway. But I knew I wanted to be on the right side so I did not have to go directly over the Road bunker. (The pin was right behind the bunker.) Unfortunately, it was bad time to hit a block fade, and I lost my only ball of the round in the gorse (which I thought I could carry...excellent deception off the tee...)
If you look at my pics of the par 5 17th on the other Old Macdonald thread, you'll see another tight landing area for the "A" line: right of the center bunkers and left of the rough, and you must carry it 240 to get to this spot. It was maybe 20 yards wide there and narrowed the longer you hit it. This time I hit an excellent power fade off the bunker and was rewarded with a birdie. The safe left line means you are playing it as a three-shotter. I think this hole NAILED Macdonald's design concepts!
