Saxnoobie: in MY opinion, all of the discussions about what one thing or another does to mouthpiece sound (baffles, chamber size, etc.) is trumped by one's own embouchure and playing style. No one mouthpiece fits all.
The ONLY thing that I find consistently pleasing in mouthpieces is the tip-opening. I prefer bigger tip-openings and if a tested mouthpiece doesn't have an open tip, I ain't gonna like it . . . period.
The chamber size, the baffle design, the length of the table, etc., is all mildly interesting to me and those features are not going to make any difference to me.
I guess what I'm trying to say is that Advisor A will tell you to always use a large-chamber mouthpiece on a vintage horn. Advisor B will tell you he uses only small chamber pieces on his '24 TT alto (that would be me). Advisor C will offer another aspect of mouthpiece design. Read it all, but make your own decisions.
