With mine it seems to be a greater volume of air but at a slower rate, but over all far less effort. if that makes any sense
I have to blow my alto and tenor but I only need to breathe into the bari mouthpiece. If I blow, then nothing or a squeak comes out. People I know who play sax and has tried my stock mouthpiece just get silence/squeak to start off with. Then when they back right off and relax their throat they cant believe how easy it is. I have tried a Yani B901 and that was more like my alto/tenor in that you needed to blow.
I just asked Jane what she thinks and she says "Loads less effort and yes just lightly breathe into it"
I think everyone should have a bari
