with the 5mm, if you need it to flow through any 16mm blocks (like I do in the take-up system in my front beam), you will need to put the eye splice in the core and not the cover of the Dingy Control. I did mine both ways as an experiment and not only was brummel splicing the cover a gigantic PIA (it's very tightly woven), it took a while to loosen up and it's still a little sticky getting through the blocks in the beam. On the other end, I did a tuck splice of the cover into the core and then eye spliced the core. That worked well.

The amsteel that connects the two makes a really strong connection so that we don't have to panic if we see it sneaking out of the beam. We still try to keep it out of the loaded part of the line but we know we can tug on it pretty hard without worry. For keeping the square knot fairly reliable, I heat the bitter ends of the amsteel with a torch so that it mushrooms the material. That mushroom will catch in the knot and keep it from coming undone if it slips that far.
