Weymouth bit from Bombers.

The Weymouth shank applies pressure both on the poll and the lower jaw. The Weymouth is made with a flat surface, attached to the mouthpiece, which allows for a close and stable fit. The width of a Weymouth should be slightly less than the Bridoon, Bombers suggests 5 mm. The four available ports have been scaled according to each width, ensuring an exact fit.
Happy Tongue Straight is a solid mouthpiece designed to relieve the tongue, but it is not curved. This makes it somewhat firmer than the curved Happy Tongue.
