I am using the V16-S on a Yanagisawa TW02 tenor sax, with Legere synth reeds. The results so far exceeded my expectations!
The tone produced steers toward bright, while still allowing for plenty of expression and tonal variation. The mouthpiece feels extremely free-blowing and works well across the entire octave range. It helped me especially with the palm key notes, which now are easier to blow and with more body. Overall I am very happy with the purchase, also considering the price, which is far below alternative metal pieces from brands that are nowadays heavily advertised on social media and, most often, ask for double or more the price of the V16.
