I like the 6.5AL for baritone. I think it is a good compromise.Dave Euph said:When I'm playing baritone (I must admit I'm not a big fan!) for the uni Brass Band, I use my trombone mouthpiece, which is a Vincent Bach 6.5AL. The trombone mouthpiece is basically just like my euphonium mouthpiece but with a smaller shank.
I don't know what the general size is, but mine does feel a tad big for the instrument.
