I always do the farmers eye cause its easy. I can do one faster than putting clamps on. But always leave the tail long and use electrical tape. Nothing to grab like the clamps. But I dont use cable much at all.
I know that most say this eye is 70% but I have never broke an eye.....always the cable.
Last time I did up any cables it was 3/8 cable I think. We were pulling down an old barn. I made up some long cables to tie the near wall to the far side wall up in the loft. Otherwise, we figured we'd just pull the near side wall out and have a barn still standing that would become ever more dangerous to re-chain to.
It was an endeavor getting a stubborn old barn down, but when it finally came down and we dug the cables out, one of them broke, but the eye didnt let loose.
I have broke cable a couple other times, but never the eye.
