I only make sopranos in one model, the Fmaj7. The Fmaj7 has no baffle, it is straight down the bore from the tip whereas a baffle protrudes into the bore and constricts the airflow creating an artificially bright sound. The lack of a baffle releases a lot of back pressure and allows the sound to flow unimpeded. It can then play freely and open in the throat. Plays more like an alto than a typical soprano mouthpiece.

 Tip openings are as follows:

.055", .060", .065", .070" and .075".

    RUBBER, known as EBONITE, is imported from Germany and contains no plastic in it's composition. Mouthpieces with added plastic make the sound thin, bright and edgy, it has a notable lack of warmth and control. Also the pitch of a plastic mouthpiece is less stable whereas with rubber it's spot on even when you blow hard or are yourself a blow hard, ha. Rubber creates a rich warm sound that resonates freely, even with the DD baffle.  Other good qualities of rubber are that it plays well in tune and can be played in a variety of styles and dynamics.

    WOOD is African Blackwood from a government run reserve in Tanzania. It is an exotic wood and used for most woodwind instuments like the clarinet and oboe. Like the sirens in Greek Mythology, it is beautiful and luring, but dangerous ... it's prone to warping and sometimes cracking. Two refacings are included in the price plus $10 shipping.
