I just picked up 25' of amsteel blue 1/4" in gray color on friday (8600 pound break strength). over the weekend I cut into three equal sections and did the did the brummel lock, melted the other end.
I tried the loop in the archery talk link I posted above (without modifying the W bracket on the leverage stick) and it worked on my trial run. have to take it out to the woods and put it through a real run and see how it does.
edited: oh and I used the ends of some old swaged XX75s as fids and they worked awesome.
