Large shank
Match it with a trombone that takes a large-shank mouthpiece.

Independent shopping perspective
Built around the Heritage Series mass-and-wall design, the gold 6AL pairs added mass near the throat and backbore with thinner upper walls. In use, that approach is intended to retain sensitivity and response across dynamics while supporting upper-register articulation. The 6AL configuration uses a large shank, medium backbore, 25.40mm cup diameter, 6.80mm rim, and 7.20mm throat. Its voice is described as big and full, with an even tonal character and improved high-register performance.
