My first choice would be a line of electric fence along the top of containment fence. Make sure they touch it once so they know it shocks. Horses have excellent memories and will remember to avoid the wire. If that is not possible (if the property owners say no) then hobbling would be a "friendlier" choice and more acceptable high lining. With hobbling they can still be pretty mobile, but it will prevent jumping. I hobble older mare when we camp even though she's picketed, since she quickly figured out that if she's not hobbled she can, over the course of the night, use her 1200 lbs to work the picket pin out of the ground. You find that once they get use to the hobble they become quite mobile. Move slower, but still pretty mobile so that they can move around the pasture and graze as if they were not hobbled. High is too restrictive for me and think about how it will be for the horse if you don't let them out for a very significant period every day. I don't even bother to train for high lining since hobble and picket training is so much easier and I like giving my horses the ability to move around some and even graze ii there's grass available (i.e if it's not January or early Feb LOL).
They're always going to be bigger and stronger so you better always be smarter. (One of my grandfather's many pearls of wisdom)
