Bombers Loose Ring Tube Happy Tongue Straight. The Happy Tongue Straight is a solid mouth bit which is ported to relieve tongue pressure but is not curved. This makes is slightly stronger than the curved Happy Tongue. The Happy Tongue Straight suits a horse with a short mouth / smile. This is by far our most successful design – we recommend for all young horses and those that show tongue sensitive signs. The 4 available ports have been scaled according to each width. This ensures accurate fitting over the bars and eliminates the rocking movement which occurs when the port is too wide.
