<font color="red"> I would not use vinyl fencing of any sort for horses.

</font><font color="blue" class="small">( Why not? I see it used for horse pastures quite often. I think the logic is that the vinyl rails are flexible and if a horse bolts through the fence they will just pop out of the posts rather than staying rigid and injuring the animal. )</font>
Regarding Vinyl fencing, assuming you're willing to pony up (pun intended) the additional cost, you must take into consideration your climate.
If you've got 'Winter" where winter means Snow, Ice, Howling winds and prolonged freezes, I've seen the vinyl shatter in cold spells.
Also, and often overlooked, never make 45 degree corners in your paddocks, especially if they are smaller fields. I've never tried softening the corners with vinyl boards, but I bet it would difficult.
The alphas can trap other members in these corners and all hell can break loose, easily resulting in broken fences AND horses.
Here's a look at our 4 board/batten. Note the corners. The posts are PT pine at 8 ft. with 4 board Oak, untreated. This is a 20 year fence with low maintenance. There is also an inside batten on each post where boards butt up against each other.
This was approx. 8$ a foot 2 years ago. It's strong, durable and is equal to or superior to the eye.
In the background, is Penny, a Quarter/Percherone blend. Sweet, scared, and 1400 lbs of thundering love. Everyone up here who sees her wants to Team Pen her. I guess they figure she'll scare the daylights outta the bovines.
