Vandoren Classic Blue Bass Clarinet 2.5

I have been performing and using Vandoren Reeds as a professional musician for 30+ years on the clarinets & saxophones.
On my regular bass clarinet set-up (a vintage Vandoren 2), I usually use 3.5 Blue Box Vandoren Reeds; but I am experimenting with a larger mouthpiece (Vandoren B-50) for jazz/commercial, and I will, upon expert recommendation, begin with the 2.5 Vandoren Blue Box to use on the Vandoren B-50 bass clarinet mouthpiece.

I use this reed with a Ernst Schreiber EPE JM mouthpiece and a Selmer Concept on the Tuyama Low C bassclarinet. Response is very good.
