You probably already know this, but I will mention it anyways.

There is a difference between "fenceline feedbunk cable" and wire rope(cable) that is used for towing or overhead lifting.

 The fenceline feedbunk cable uses fat wire and only about 7 strands or so. Dad and I had to go to a concrete place that sold feedbunks to find the actual fenceline feedbunk cable, you just can't go to the hardware store and buy this style of cable off of their shelves.
