Off topic but in regards to this response… I find sensitive horses do really well in them. 9/10 out of ten, I prefer rope halters to chain. Sensitive horses tend to be sensitive to correction, so it is crucial you have perfect timing and release… which the rope halter is very good with. Especially useful if you have a sensitive horse that has learned to become a bully and is quite defensive with the chain.
If you don’t manhandle with the rope halter, the horse hardly knows it is a rope halter anyway. It is lighter than a leather halter and “at rest” is hardly more than a hat to the horse. If you are worried about the ‘bite’ of the rope across the nose, just put vet-wrap or fleece or sheepskin over it.
With all of my rope handling I only ever had one horse test the end of the rope and he did it once and not again. Rope halters give much more control than a chain does, just my experience, as I’ve been inclined to lunge horses that have a history of running away with the handler in them. My black rope halter has stopped a runaway train on more than one occasion in a way I am not confident the chain would have.
Rope halters definitely have much more control and dexterity than a leather halter w/ chain - and, the best part is that it is immediately slack once you release pressure as there is no leverage or shanking action - release the pressure and the nose is immediately loose again. Chains do not immediately release, as they by design constrict around the nose by being pulled taut through the metal eyes of a halter - the metal eyes actually prevent immediate release, and with pressure applied the chain is often too heavy to revert to previous “loose” form.
I find chains do very little to teach a horse to respect their handler, as it lacks the immediate release and timing that is so critical for rewarding or encouraging good behavior. You can get the corrective measure right, but the release is slow and the horse doesn’t learn much from having the end of its nose bitten off with no release in sight…
For that reason I never put a chain across any of my horses - kind of an empty statement since none of my horses ever need chains in the first place. The chain in our barn is reserved for only one thing and that’s twitching for medical reasons. Other than that it is dusty from lack of use and in the same spot it’s been in all year.
Rope halters are great for teaching respect in young horses that have never had to respect a handler before. Great for big bargy horses too, that have been dulled or don’t react much to pressure or shanking otherwise. The thing about the rope is that it is extraordinarily malleable: you can shape the correction however you want. With a chain, the correction is pretty much the same strength or bite, no matter what… which can be a problem for sensitive horses that only need a light correction, or dull ones that might need a huge one.
The other thing that is of benefit is that in the case of emergency the rope halter is easily cut with the dullest of pocket knives - chain and leather are much harder to cut through.
What I dislike about the rope halter is that some are not break-away, and people hard tie in it. That is an accident waiting to happen. I would only tie to twine in a rope halter.
