Thanks, this settles the argument I have with a friend. She says she does not believe in using bits, she rides naturally, yet she uses a mechanical hackamore. I am currently using a full cheek snaffle, to work on my girls stopping issues, but she does fine in a halter or sidepull hackamore. I mistakingly used a tom thumb on her when i first started and another friend almost had a heart attack. Now I'm on the right track I think, is there any advise you can give me on stopping issues, going is not a problem unless it's something scary or a male horse (stallion or gelding, she ain't picky).
