La Voz reeds are very similar to V16’s.
I’ve only got 4 mouthpieces, and i’ve found out in general there are usually 2 different reed brand types that are roughly equivalent.
my local music shop is run by staff who play sax’s in orchestras and jazz bands, and i often ask them what a reed is like, and they can roughly tell me how different types compare in terms of strength and which ones are better for different styles of playing.
At the end of the day you still have to try them, and keep a cross reference chart of similar brand types/strengths that work for your mouthpiece. But don’t be surprised if you change mouthpieces, they don’t work as well
