My index is currently 12.1 (probably a 14 or 15 hdcp at HC), and I shot a 90. I admit that the greens got me. I was hitting the ball fairly well, but the subtle countours on the greens got the better of me. If I had been putting well, I'd have been around 82-84.
We were spending more time looking at the architecture, especially around the greens, than worrying about pure scoring, which was great - that's why we were there.
We had a great time.
