My Selmer Series 10 came with a Selmer S mouthpiece and a 65mm barrel. I recently purchased a Selmer C85 105 mouthpiece which plays great for me. However, with the 65 mm barrel, it plays flat. Looking for a shorter barrel or any ideas from the community.
The 64mm Moenning Buffet is my got to barrel, although I usually buy them used on eBay when they pop up. I love the reverse taper inside that gives me a bit of a boost in sound projection: YMMV.
