The Jr cow horse is a good bit to introduce your horse to gag bits. Its not to aggressive but still has some slide. It also works pretty well when teaching your horse about side pull vs back pull. Like I said earlier in the thread, I teach my horses to one rein stop, so that's important to me. The only thing about it that I don't like (and why I would only use it as a training bit) is that you don't have as much independance side to side. Because it has such a short slide it will engage the whole bit with moderate pressure. All in all, not a bad training bit though, but not something I would run in.
my horse spins with the tom thumb. I never said a tt is the best bit ever. Im just saying its not crude and pointless. Infact it is very easy on a horse mouth. And thank you very much I am in training to be a veternarian and I train horses all the time. I can turn on a dime. So go ahead think what you want.... ill let you keep thinking that.
A horse can spin with any bit...Even without a bit. IF they know how to neck rein.It's not the bit that makes them spin.
