For me this mouthpiece seemed to work well with 'larger' German rotor F tubas. I liked the rim contour and interior diameter better than Perantucci mouthpieces for my mouth structure.

If I remember correctly, that is the mouthpiece model that came with my Getzen Meinl-Weston model 30 CC. I always thought it was more suited for an F tuba.
