A myler comfort snaffle, after two years of head tossing, chomping, and being agitated with bits , with teeth done I will add, I tried a myler full cheeked comfort snaffle today and shes been the best today thats shes been in two years, was very happy in her work, no chomping, no head tossing needless to say have ordered one on trial from the horse bit bank, just wish I had sussed it sooner after many failed attempts at different bits
