Their thoughts are typically not well translated in these ads. I'm currently using an Eastern Music Soprano sax and mouthpiece, and an alto neck. Pretty good stuff. I tried two of the mouthpieces and they both played well, but I went back and got a bigger tip. The Chinese mouthpieces I have seen use a different numbering system that is way low - a 7 is about a 4. I ended up with a 12 but its not that open.
