Recently I acquired a Selmer Soloist D for tenor, and I am absolutely in love with it. It feels really comfortable for me in both jazz and symphonic settings, whereas I used to switch between a Link STM 7* and an s80 C*. I'm looking to make a similar move for a soloist alto mouthpiece, but I am hesitant on which opening to order. From articles like http://www.saxontheweb.net/Coats/mouthpiece.html#sizes, some of what I've heard Mojo say, and from just looking at tip opening charts, it would seem that a D would feel more open on alto (same as a link 6) than it does on tenor (same as a link 5). Obviously the best way to decide is by trying them, but I have to order them online as I've never seen music stores carry soloists. What would be the equivalent size to a tenor soloist D on alto? C*, C**, or D?
