I'll answer first. I've been using Vandoren products for a good 3 decades now. Currently, I'm playing Vandoren V16 mouthpieces on the alto (A9) and soprano (S8), as well as a B45. on my clarinet, and B50 on bass clarinet. I've been using V16 reeds (3 ½ strength) on my saxes, but on my clarinet I've been using Legere synthetic reeds.
I am considering checking out a Selmer Soloist on soprano, as well as a Jody Jazz on my alto sax.
What does your setup look like?
