Thanks for the feedback. I've read the FAQ and I understand many folks aren't fond of Gemeinhardt flutes. I'm not boxed in to the idea of buying only this brand. I'm curious about the history of these two models. I'm just looking for a decent flute for high school marching band.
I'm not concerned with putting the finest quality on the football field.
I happen to have a well-maintained 3SHB from the early 90s that plays much better than some modern day open hole models from other brands. This doesn't mean I only consider Gemeinhardt, of course. I am aware that many advances have been made since this instrument was produced and that Gemeinhardt made some lesser quality flutes at one time.
