OK, if you were about to start a 6th grader beginner, a rather large and robust one, who shows moderate but not burning interest, what mouthpiece would give him? Or what criteria would you use to decide on a mouthpiece? I've never read a really satisfactory reply to this question (at least satisfactory to me). Is there a better idea than, well, you know what? Let's also assume one is willing to spend a little extra, but not bet the farm at this point, monnetarily speaking... Is this less important than I think? More important...?
