Hello! I ride Western and do mainly barrels and other western show classes and games and trails, so I need a versatile bit. I currently have my POA in a Tom Thumb, but I don't think it's right for him. He's 10 years old and I think, personally, he needs a little harsher bit. I'm having some attention problems with him, he doesn't like to listen very well and all of the sudden he's a little hard-mouthed (and he usually is pretty soft) and I just feel that he needs a harsher bit.
I have heard that many like the Argentine Snaffle? I've heard that it's a little harsher than a Tom Thumb, but still has the broken snaffle part so it's not so harsh... If you don't think that an Argentine snaffle is right for me, what do you suggest?
