If you want to bring Black Mesa into the conversation, and you want to say #7 at Old MacDonald is controversial, then you have to say #17 at Black Mesa as the predecessor of #7 at Old Mac is controversial.
Garland:
I had to think for a minute about what the 17th at Black Mesa was like; I never thought of it when we were building #7 at Old Macdonald, but I guess it's somewhat similar. Then again, I never would have picked #7 at Old Mac as a controversial hole. It's a difficult hole, as it was hard to reconcile the steep climb to the green once we decided we were going to go for the ocean view; but I figured the view would quell any resentment over the difficulty.
Old Macdonald certainly has its share of controversial holes. I would guess the most controversial to be #10, #12, #16, and #17, although at least 16 and 17 have their historical precedents to lean on. That's probably the highest number of controversial holes I've built in a while -- which is testament to the input of the others on our design committee, and to Mike Keiser's increasing tolerance for a bit of controversy.
I agree with the sentiment that every course should have a bit of controversy, and I don't think it should be confined to just one hole, which some architects throw in as a token gesture every now and then to prove they can do it, too. Getting the balance right is the difference between building a great course and missing the mark ... though, like everything else in golf architecture, the right balance is subjective.
