With a Dacron lanyard, it might be a self-solving problem, mostly because the Dacron should be at least 3 times the diameter of the HSR.
Fair leads,

PS,
You can see a video of a shackle break here:

Two things:
1) The Samson taper is strong and easy. 1 fid length back cut e/o pair for total of half the strands. Then taper the very end with a shallow cut or by removing half the remaining strands working away from the end
.
2) The cutting of line I was worried about is as follows. Say you have some 7/16 StaSet at 6600 pounds and want a soft shackle of similar strength. For thin line you have 260% line strength so 1/8 Amsteel is a perfect match. The question is did you just introduce a new failure mode where the 1/8 inch soft shackle cuts through the 7/16 line causing a failure in the splice of the StaSet.
