At my place the fences do double duty. Keep the horses in, keep everything else out. A heard of elk will run right through everything except barbed wire. They'll even run through that if it isn't maintained. Moose are stupid! If they touch an electric fence they charge into it. I can't tell you how many times I had to go down the road and retrieve the fence.
It's been my experience (and my vets') that T posts injure more horses than the fence. Now all my T posts have caps.
Most fence injuries happen in the corners and it doesn't matter what kind of fence it is. A lot of injuries happen from the horse running down the fence line and slamming into the corner. If we can avoid corners by rounding them off, or angling them we can avoid a lot of injuries.
Yea, I have had Elk take out our fencing; usually just the top wire, but a couple of months ago, I watched a confused young cow-elk take out about 50ft of the neighbors fence after failing to clear it with a pitiful attempt at a jump. (She then trotted away with no visible damage; yet another argument for smooth wire.) The neighbor horses were quick to take advantage of the gap, and within minutes, all four of them came trotting up the road to visit with/tease mine. They know me, and it didn't take too long to get a catch-string on the Alpha horse "Carlos", and lead him (with his herd straggling along behind, and mine bellowing encouragement across the fence) back home.
Rosy, the above mentioned Bovine, just leans on the fence until something gives. George will sometimes stand on the middle wire until it breaks, and then duck under. I double up on the "stays" in places where he might be tempted to break out. Fortunately, we live in a relatively closed neighborhood, so the animals are fairly safe no matter where they wander. If you are on property adjacent to a busy road, I cannot recommend a single run of wire-on-t-post fencing, 'cause they _will_ go thru it eventually; count on it.
And T-posts. They tend to be kinda sharp anyway, and after driving them in, they often develop razor sharp edges. They will cut your gloves, they will cut you, and they will assuredly lacerate your Equines.
There are a variety of T-post caps available; some are for use with a hot-wire, but unless this is a useful feature, just get the fitted plastic ones: https://www.valleyvet.com/ct_detail....oaAry_EALw_wcB
When I put in new wire, particularly if it is in a new place, I always adorn the top wire with a strip of surveyors tape to increase its visibility. This can be removed after a month or two, once the critters have had a chance to learn about the new fence.
