The horse has issues with its head and the neck reining isn't up to speed because she won't turn with leg cues. Which means I need to direct rein on occasion, which with the tom thumb just results in head-tossing and frustration. So here's my question: the bit is like the one pictured, so it has an additional ring directly next to the mouthpiece. If I attach the reins there instead of on the end of the shanks, and leave the curb chain on, how much less harsh will the bit become? Or should I abandon the curb chain entirely?
