What do you prefer?
My horse is currently in training (almost done so I can bring him home :D). Mostly in a halter which I ADORE that he can ride so well in one and be responsive. She does some work in a plain snaffle but I can’t imagine that riding so far would be comfortable with metal jangling around in your mouth. While he works great in either type, I think bitless is more comfortable.
So I chose to go bitless. We have ridden in just a rope halter with 2 knots on the nose band and I also have a rope halter sidepull. I’ve been thinking of going with a bosal but I am unfamiliar with them.
