You completely ignore the fiadore. Without it, the heel pf the bosal drops against the chin. When a signal given, the heel of the bosal has to be raised to make even light contact with the jaw and nose. The result is that it takes a mili-second or two for the horse to get the signal. A "sloppy" signal produces a "sloppy response. A bosal should fit around the nose exactly like a hat. If it does, the horse can feel a signal by simply wiggling a rein. A pull is not required when a bosal fits correctly. I have been training bridle horses since I was 30 (over 50 years ago) and know whereof I speak. I am currently in the process of starting a 3 year old Arabian gelding that is going to eventually make a superb bridle horse..
