If my horse fights so hard that it gets rope burns from the halter then it will probably learn something from it and not fight the next time. The reason that nylon or leather halters don't cause rope burns or other things on a horses face when the horse pulls back is because they break before they have a chance. I have never seen a horse break a rope halter. It is the only kind of halter that I have and I see no reason not to use them to trailer with. Just like curb bits, whips, spurs and other tools any halter can cause harm if not used properly.
