Labelled by many people as too big, I have to push back and say this mouthpiece really suits me and my flugelhorn. I'm used to the Schilke 22 and 24 on my trumpet. However I find the 24f easier to play vs the 24 on my trumpet. This rim and cup size is more suited to the deeper more rounded sound of the flugel, and of course is deeper than it's trumpet sibling. Slotting is improved, tone is full, super smooth and wide dynamics easier to modulate.
