The SKB's are nuke proof! I've had mine all over the country from coast to coast and N to S with never a worry. (unless it gets lost!) Go with the double so that you've got room to pack your boots and camo in with your bow. (You only get 50#'s per bag now so you have to make sure that you can get 50#'s of gear in your case or you'll be paying for an extra piece of luggage. Which, if it happens just once, will more than offset the extra cost of the double case!)
