I have Centaur HTP fencing and think it is great. It must be properly installed, however, and anywhere there is a problem with it that I have seen, it has been installation error. Like mine – the dopes did something really stupid on one corner, didn’t brace it properly at all and that corner needs to be totally rebuilt so until that happens, I can’t tighten the rails and they do sag a bit. We are fixing that this summer. The manual is very specific and clear and the company is great with help over the phone, but our installer apparently decided to “wing it” and failed (yes, we should have noticed, but didn’t, until it came apart and we are just fixing it rather than involve him again as that wasn’t the only little problem with his work).
I also really like the White Lightning (coated electric wire) from Centaur and would be inclined to go with several strands of that topped with one of the Centaur HTP (5" wide) if I do any future fencing. It would be less expensive and I still think it is very safe and nice looking.
If we had to build from bare land again, including fencing, I wouldn’t hesitate to do Centaur again – the cost is greater, yes, than some other types, but I think it is worth it. We’d just do it ourselves, watch over the installer better, or make sure we get someone with experience with the stuff.
