This bit gives you more flex and bend than the original lifter. I love the short shank for starting colts and the long shank for running the more solid horse. It comes in all four mouthpieces giving you lots of options. Brittany Pozzi. This is a thin, smooth snaffle so you will not sore the corners of your horse’s mouth up, and you will not get that dull feel that you sometimes get with a bigger mouthpiece. Mouth: 5 Brittany Pozzi. NOTE: This bit will rust when exposed to moisture. This creates a sweet taste in the horse’s mouth and promotes salivation.
