Alas, I cannot try it out because I no longer own a bosal. :"( I think Dad has one laying around the tackroom somewhere but it is just the bosal. The headstall got broke many years ago and we just never replaced it and the horsehair reins have been changed to the snaffle bit he used on his belgian mule a couple of years ago. I may just have to look around though and see what I can find. However, after all my horses are broke, I start riding them in rope halters often.
