Great.
Just remember, with any other than bits, the trick is in the immediate release to any you ask.
Communicating by the nose is about asking, never pulling, ever, or the horses learn to stick their nose out and run thru it.
Many horses prefer that to a bit, any day.
We even use our grass rope hackamores with our older horses whenever possible, they are so comfortable with them.
With bits, a rider can haul around and control a horse by sheer pressure on the mouth or leverage.
The rider can have impolite hands and get by so much.
Not with bosals, if a horse ever tries you and you pull back and try to hold, you are teaching them they can ignore you.
From on top of them, you can’t get enough leverage on the nose, as you can with even a halter if you are on the ground.
It is all in teaching right, teaching light cues and sticking to them as a rider.
Ham handed riders don’t get along with bosals for long.
Also, your body is already telling a horse what you are going to ask, so what you eventually get to “say” thru your reins is confirmation.
Nice that it worked so well for both of you.
How about some pictures?
