Hello, I am working with a student for his bari setup and we just bought him a used BL3 from a fellow SOTW member. What he needs now is a ligature to fit the BL3, seeing as he has come from slim stock plastic mouthpieces. What do you recommend as a ligature for this mouthpiece? I don't need him to buy an expensive Optimum or M/O ligature but rather, something reasonable and simple. I am unsure about Rovners, they didn't fit my tenor TL3 well at all. What does the forum recommend?
