Query: Good and economical upgrade of a Student Bb Calrinet

My daughter is a seventh grader. She has been using a Yamaha YCL-250 Bb clarinet for three years. I was thinking about buying a better horn for her but she did not want it. She was afraid she would drop the wood clarinet. So I bought this mouthpiece together with a new Rovner ligature. I am glad I did. She can hit some high notes that she was not able to.
