The farm I manage has electrified coated high tensile, and here at home I had non-electrified coated I high tensile. I MUCH prefer the electrified. The electrified coating is different, less slippery/stiff. I have had horses hit the electrified and bounce off, and I have also had horses take it down completely. Zero injuries, the electrified does not “spring back” and coil up, and I do keep it TIGHT.
The non electrified at home DID coil up when pulled down, very dramatically, and likely would have entangled a horse’s leg. None of my animals respected the non-electrified, they all reached thru to eat grass on the other side. In fact, all of the neighboring farms with non-electrified share the same issue, their fence looks horrible all the time from horses stretching it out, and often horses get loose once they realize they can just “walk thru” the fence.
As far as installation and maintenance, the hardest thing is bracing your corners and ends, after that it is SIMPLE. I prefer to install my tensioners at the ends/corners and NEVER in the middle of a line. I think it looks trashy to have a clean line of fence interupted by a tensioner that weighs the line down and just looks unsightly. My tensioners are also planned out and placed at corners and ends that are the easiest to access, not in the back of the field. NEVER install my insulators with staples or nails, dear Lord are they a PITA to remove when the insulator breaks. Star head screws are your best bet with insulators!
