I have been using the Gallager 6 conductor poly twine. I use the pigtail step in posts, use kencove yellow insulated hooks and insulted alligator clips. I hook one insulator end to the perimeter fence, then walk to the interior single strand hot fence. I then tie off the end with a second insulator. I then walk back and place a pigtail post every 20 paces. Finally, I connect one end of the line to a hot line with the alligator jumper. That way I don't have to shut off the fence and I don't get shocked.
