Cheekpiece: The Full Cheek is valued for its steering/lateral assistance, mouth stability, and comfort, making it a popular, FEI-legal choice for young horses learning directional cues, horses needing extra straightness support, or driving horses — rather than for any leverage or "stronger" stopping power, since mechanically it functions as a direct-pressure snaffle.
Mouthpiece: A Single-Jointed Rubber bit keeps the classic, direct communication of a single-hinge mouthpiece while softening its typical sharpness through rubber's natural give — making it a useful option for horses that want the clarity of a single joint but need a gentler material, though as with any rubber mouthpiece, its softness may invite leaning in horses already prone to that tendency, and it should be checked periodically for wear.
