If a horse is broke it should carry a bit. Bitless set ups are for starting a horse ( like my basal hack) I know what bit is going on my horse and will double bridle her to get used to it before it is our main communication aid. Unless there is a physical problem with the horse, it is your job to teach it to behave with whatever bit you want to use. My wife's horse has scars on her lounge from her previous owner not caring for her teeth, she will be a bosal horse the rest of her life. My mare will be a true bridle horse, carrying a spade, she doesn't have a say in it. If she acts up, it only means more work for her...I AM THE LEADER, WHAT I WAY GOES, I AM THE MORE INTELLIGENT LIFE FORM. I will not be cruel or heavy handed, but I will be firm in my insistence.
