It's not really that we couldn't bit her, or that we're lazy. But I'm a firm advocate of if it works, why mess with it? Even my friend who used to breed and show dun QH (on a national level) asked me why I thought I should change Jack's bit. My answer, at the time was because I was told it was ababy bit, and he needed another one. She asked me why, and I had no answer, lol.
