Here’s the Noavel if it is what you were looking for OP: http://www.hoofnail.com/headstalls.htm
Never knew it existed until I was introduced to it last week by a farrier who uses it on his tougher horses to quiet them. Seems like a pretty ‘strong’ halter though I could see its (limited) use with certain horses (particularly as you develop them to be better). One thing that concerns me is that if the horse tosses its head or such, it seems it will be automatically reprimanded, regardless of whether that is your intention or not.
As for the CA halter, ‘you don’t know what you don’t know until you know it’ - if you haven’t used it (I haven’t), I wouldn’t be so inclined to criticize it as just another expensive rope halter. I certainly notice a difference in response between different halters myself so wouldn’t be surprised if the CA halter also produced a different response than some of the other halters I’ve used.
Stoicfish, every horse’s head is different in size… hence different sized halters so the knots are placed appropriately for the most part Remember too those knots are not exerting any pressure when the horse simply stands quiet or even tosses its head, only when the horse actually leans into the knots.
