The Pee Wee is the only Bit with a floating mouthpiece. This feature allows freedom for the horse's tongue. Your horse can safely swallow, breathe, chew and move it's tongue without any interference from the mouthpiece because it floats above the horse's tongue on the large rings of the Pee Wee Bit. This results in a very secure and relaxed horse.
The baucher is most often seen in use for show-jump and dressage phases in eventing. The reins attach to the eggbutt-like ring at the mouthpiece, while the bridle cheeks attach to the smaller ring. This makes the bit sit flat against the horse's face and is quite fixed in the mouth. Pressure is concentrated on the bars, along with some slight poll pressure.
This model features a french link mouthpiece, which lessens the "nutcracker" action experienced with single joint snaffles, meaning that there will be less palate and bar pressure than the single jointed model.
