Full cheeks are useful for green horses or young horses as they can help with steering. Shanks on the bit create a positive action against the horse's cheeks when asked to turn. The full cheek design also prevents the bit being dragged through the horse’s mouth.
The Waterford mouthpiece is comprised of a series of ball shaped links, making it completely movable in all directions. This is particularly popular for combating issues such as leaning, taking hold of the bit and jaw setting. When the horse tries to take hold of the bit the mouthpiece collapses, leaving the horse with nothing rigid to take hold of.
The mouthpiece works to distribute pressure over the tongue and bars of the mouth. Coupled with full cheeks, this bit is a good choice for a stronger horse who still needs guidance with steering. Should be worn 1/4" - 1/2" wider than standard to work effectively.
