My pull-throughs are made from a piece of old cotton wash cloth or dish rag fastened in the middle of a six foot length of 40-50 pound monofilament with a tightened clove hitch.
If it gets stuck, which it never does, you can simply pull it back the other direction.
They never break, are cheap enough to carry one in every piece of hunting gear, and you won't even know you have it in your pocket.
Best of all, in a pinch it can be used with a large single hook for pike.
