He's currently in a cob bridle (but on the smallish size, it's pretty tight on him around the browband and throat lash. The bit I've started him in is a 4 3/4 inch straight bar happy mouth. He'll be put into a D-ring with rollers or a full cheek with rollers like Flirt, once I start formally mouthing him. At this stage I used the Happy Mouth just to get him accustomed to having a bit in his mouth.
