i believe trout fishing schools are great value, but then i started as a complete beginner. y'know, you could call and ask. find out how to contact the person who will actually run the school, be honest with that person about your own fishing, and see what s/he says. some schools are more flexible than others; most have enough instructors to go around. your own tolerance for sitting through lessons on something you know a little bit about is also part of the equation. i wound up doing the second day of my trout school over again, and learned much more the second time.
