I'd go cargo in a heartbeat. Nothing against SWA but I'd say if the odds are against someone it'd be the company that isn't as diversified as FedEx. At least cargo outfitters have more areas to draw revenue from, can work more with govt contracts, don't have to deal with canceled flights due to a 3hr limit like the majors, and have the additional international exposure which is huge.
However if you really have those options available then good for you man
