I currently play a Selmer Soloist C*, not a soloist style, on tenor. I play mainly legit and at church, but I am at the point to where a Vandoren blue box 4 is still not quite hard enough. I was wondering whether I should have this opened up, or keep using the hard reeds? I like the overall sound, but I don't feel like this moving up in reeds is the best idea. A 4 is almost too soft. Should I have this refaced? Or should I sell it and get a different mouthpiece?
