I just got in some SS tube thimbles to try out. These are a little pricey at $45 additional to the price of a winch line. But they have some added benefits.
A) No rust or corrosion.
B) You can get the ear of a 3/4" shackle through it
C) I believe it will not go through a fairlead. I still need to verify that.
Onto some pics...
