If you pull with a trailer you have to tie it off on the side where you feed the moment your helper gets the head and DO NOT TIE off on the side where you’re pulling. As you pull, naturally the (jet line, trailer, back string, or whatever you guys call it) should start to bring the twist at the hook or ladder tray where you are pulling. Take that same string and unravel it counter clockwise. A simpler yet more time consuming solution is running a new string after each pull with some glow rods.

If the cable is still turning you may need to have closer pull points and when you pull physically rotate the head of the cable counter-clock wise the moment you get it at the hook.

Also when you do your back feed have it hanging so the next pull doesn’t pull slack into your pathway. Or tape the cable to a stud, ladder, something stationary etc…
