I shot it 5-6 years ago in a league. It was neat, but had the drawbacks everyone already mentioned. One thing that was a downside was the people who would shoot it 2-3 times a week before league (the same disk that we would shoot that week), so they would have all the scenarios memorized and when the shot would present itself. Or the ones who would get there early to watch the early groups shoot and memorize the scenes. Really wasn' t that competitive, because they all had the advantage over those of us who were seeing it for the first time.
