okay, so my old mouthpiece was useless and i need a new one
(for my alto sax)
i am trying to decide between
bobby dukoff d8
otto link 6*

i mostly solo (With a small ensemble, piano, drums, bass, etc)
and sometimes play in a concert band (classical)

which should i get?

and how is the numbering (on otto link) and the * sign change the size of chamber etc?

please help
