Well I myself am a student. I hate making theses types of decisions. It's kind of like the Robert Frost poem "The Road Not Taken", If you choose to do just band you will never now were you might have gotten with choir Or Vice Versa What I would say just as a person and in my opinion is just do what you like most. Or if it is possible to juggle the two then do it. Because I want to take choir but I can't because of my schedule. As for the leadership thing, If you like it in band and you are a leader and looked up to in the Band I would recommend staying in Band because you should ALWAYS do your best whenever you do something not half way. That is just some of what I think, Just remember that is my opinion. Don't let anyone make the decision for you, ALWAYS make on your own but be sure to think it through.
