Most/All(?) Winch Ropes have a Steel Gusset Tube Eye - That is perfectly fine to use with a soft shackle.. or a soft eye loop.
Bubba and Safe-Xtract Dip their soft Eye loops for ease of use, that and the regular soft eye loop are fine to use alone as well...
I guess what I am trying to say is, no need to over engineer it when there is a solution already on the end of your rope.
FWIW...
There is an international standard system for Rope...
Dyneema and Plasma ropes are pretty much the ones used in the offshore lifting and boating industry, both are HMPE fibers...
Offshore is Where synthetic winch and dynamic lines came from...
(Spydura is Dyneema with UHMC fibers and is for the offf roading industry, not lifting)
Nowadays there are thousands of companies making synthetic winch lines out of all sorts of materials most are UHMWPE fibers, some conform to the international standards, many don't...
For instance you can get a Chinese synthetic winch line on AMZ for $67.99... No idea what it is other than a "UHMWPE" Line - it says Dyneema in the description but that is the producing company in the Netherlands... and I highly doubt it is Dyneema just because the cost per foot for Dyneema is between $1.25 and $2 in spools before shipping of course.
Anyway, yes you can get cheap stuff from those companies but this is a highly critical load bearing line that is critical to a safe outcome when recovering...
Pretty much all the basic equipment we use in winching came from the lifting industry.. I try and stay with companies that produce for that.
I have a 15 year old Dyneema Samson Blue Rope on my Defender with a SS gusset eye (cut down to 80'), and the Safe-Xtract Plasma Line on the 200....
Pic of my d90 winch line end this is a pretty old rope with 100’s of pulls on it as well…
