Bobby Shew Lead Mouthpiece

Music Teacher here:

I have a question about the Bobby Shew mouthpiece. How does it play? I have a student wanting to upgrade from a 3c and get one for playing lead in jazz band. They sent me the mouthpiece and asked me about it. I play on a sloped mouthpiece and personally like that one and try to avoid the mouthpiece arms race. But I'll ask you guys: Is the Bobby Shew lead mouthpiece worth it?
