Today at Matthew's in Edam I tried all of their C* mouthpieces and took one home. I hope I wil stil like it tomorrow. I have gotten used to the Vandoren sound though. I might go and look for an A17 Tuesday at Bakker. If that doesn't work out I'll call it 'a day', or 'a mouthpiece'.
Matthew's never had the inquiry before to rtry more than 3 mouthpieces of the same type. Which is strange. Maybe they don't deal with professionals so often. I don't know. I am glad I found something though. I'm going to rule out the A17 as an option (it is nice and dark like the AL3 but a bit stuffy). We'll see again!
