Hi Greg,
Normally I just use the bow sock that came with it, but I have this case for flying. It holds the bow, my arrow case, my GN quiver, and has room for compact binoculars, small camera, other delicate items in Crown Royal bags tucked here and there.
It's some sort of M4 case and it's supposedly fully TSA OK'd. I think it was around $150 but considering what I put in it, I just consider it extra insurance.
I don't know if this is at all what you were looking for, but I thought I'd offer it up in case it got your wheels turning.
Thom
