I think the issue may have just been finishing. I have some of the original speed hooks, and there is a decent burr in the holes. As fine as the fibers are on amsteel, it doesn't take much effort with anything that has an edge on it to catch those fibers, especially when you add human weight and hammock forces into the equation.
I think a good polishing of the holes will help considerably, if not get rid of the fraying issue. I just haven't gotten around to it since I have so many other suspensions.
