Yes that pretty much reinforces what I thought (no pun intended). For better or worse, my wife is an environmental engineer. It's not just the resin she doesn't like, but also the fibers, and the lack of anything like the sort of filters and safety equipment the mfgs have at our house. She at one point was charged with inspecting mfgs that made boats, tubs, jacuzzis, etc. This is not one I can win...

I was thinking about something like 1/8" ABS or plywood glued to non structural foam... The gig bag I ordered is 8" deep (the one dimension that is different than the Thomann bag)--which is about twice as deep as the bass is thick at the high point on the bridge. So there is space to fill, which got me thinking about extra padding and something to add puncture and sharp blow resistance--at least to the top and bottom. In other words, the case is big enough that it got me thinking about a case within a case. All just idle speculation until it gets here ;-)
