Noseband, bit and martingale questions!?

everything the person above me said is very good and should help you a good bit. for barrel racing, that bit is a very good transition bit yes and it will give you good brakes. it seems to have a good mouth piece on it, i like that bit alot. i dont like to put narrow mouth pieces on my horses but i need more than just a snaffle or a curb. that bit should be good!
