I bought a case to fly with several years back and it has worked out great.
SKB cases a tough like a rock. Mine has held up to all sorts of travel conditions and I know several other guys who have them and they have not complained once about theirs.
I store my bows in a case at home to protect them. I have a hard plastic type like these at Bass Pro. http://www.basspro.com/webapp/wcs/st...003000_450-3-2
