We tried polytape since we liked the visibility but it doesn't last; the wires burn through where it's tied to the handles. We've used the steel spring gates, but they're expensive and won't reach across most of our gate openings(we kept 30' openings for equipment.) We have one opening where my husband used high tensile wire, he will not be doing that again; it coils & tangles when opened, there's too much tension on the handles and they wear out too fast, etc.
We stayed with polywire. If it's a permanent fence then it's tied to an insulator on a steel or wood post, it it's a temporary fence we use fiberglass T's at corners or ends of a run. The other end hooks up to the hotwire with a handle.
We also use a step-in post in the middle of the gate wire. If you have a double wire gate, it helps keep them from tangling. You can open a gate and use the post to keep the polywire & handles off the ground. Or, you can unhook the gate handles, pull the post and drop the whole thing on the ground to drive over; pick up the post and the wires aren't twisted together.
