I am not showing, just seems like it would be frowned upon for using a full cheek on a western headstall. I don't know which part of her bit she likes, which is sort of my issue. She did good in my barrel mares gag bit, and she does good in this bit. However I've tried a double jointed snaffle and she HATED it. I'm not sure if it's the pressure along the side of her mouth or the part against her tongue. She has a very soft mouth until she runs, then she seems to forget everything and a plain snaffle doesn't seem to be enough.
I suppose I don't know much about bits. But I think I may try that barrel racing bit. (I would like to have two different bits so that I don't have to switch them out constantly!)
