I disagree, when you think about it, a super thin smooth mouth peice isn't going to be any nicer than a standard twist. I like my twist I think it all depends on the horse, just because one doesn't work well in something it doesn't mean the other horse wont work well in it either. None of my horses use the same bit. Personally i'd rather have a bit that will keep me and my horse happy and content then one that I will really need to use on him. I'd rather have a bit with a lot of "power" and me not need to use it then one with little and have my horse and I get frustrated.
