chris,
My blade has the single line set up and I just changed it a little so the halyard doesn't go to the rear beam. I will be down there in early march for the performance midwinters and you can see my set up live then. It is similar to the diagram except it runs on the starboard side of the tramp. I only used it for the first time when I was down there in January and it seems to work well. It is better than the halyard/snuffer line going to the back of the tramp because it is easier to look forward when you are snuffing it.
Are you going to do this race?
Bob, what race is the 23rd?
