The Viola-on-the-Mountain pic really is great. I also love your solution to the musical-instrument-outdoors problem. I did a bit of checking after I saw this thread and found that there really are a lot instruments becoming available in carbon fiber (I found guitars, mandolins, bagpipes, flutes, even a didgeridoo). It's too bad that people in your field can't have more of an open mind about things like that though. I mean, if it sounds the same or better, what's the problem? Even that cello guy Yo-Yo ma has a carbon fiber cello.
Look at it this way, CF isn't going away, so you're just ahead of the curve!
