Recently I required a flight case (for a shotgun) and noticed that Swan were selling these at a good price:

They are "pick and pluck" foam so you basically pull the foam out to fit around whatever you want to place in the case so this makes them very flexible. Measuring it I make the pick and pluck bit about 32 1/4 inches by just a fraction under 11 inches so it might also work well for some travel rods, reels and the like. I'd guess it would just about take 32 inch shotgun barrels.
I've just taken delivery of one of these cases and it is well constructed and actually a very nice case. It was recommended to me by a mate who is in the pro-audio business and who has a high opinion of Swan as he buys their cases by the pallet load. He does also build custom flight cases but says he couldn't build this for the price.
