I have a 17 hand plus mare that was previsously used as a trail/pleasure horse. I want to use her for dressage next year. I currently ride her in an eggbutt but I don't think it's the right bit for her. She has such a large mouth and the bit is large too, and it doesn't really have that "nut cracker" effect on the bars of her mouth. It just kind of lays across her tongue because its so wide and theres not a whole lot of leverage. She's a very big and powerful horse and it takes a lot to get her what to do because she knowes she's big. I know a lot of people are probably going to tell me, "No you don't need a stronger bit, she just needs training" I know that, but people who are going to tell me that probably have not ridden my horse and understood that she is very massive and powerful and even when we contue with her education she will always be a hard horse to ride. Anyways, I am looking to find a bit that is legal for lower level dressage that provides a little extra strength without being severe. Does anyone have any ideas that might work for her? Also does anyone know any websites or stores that sell draft horse tack?
