I just recently changed my clarinet setup. Used to play a Vandoren B40/13 with #3 blue box Vandorens. My B40s were going on 20+ years old, and had both had the facings tweaked a few times. I moved to a Ron Caravan mouthpiece for a while, as it plays well with the #3 blue box reeds, but it wasn't quite what I was looking for. Got a new Walter Grabner K13* last week. That piece, with #3.5 V12 Vandorens is exactly what I wish I had 20 years ago! I feel like a real clarinet player again.
