I know you're not supposed to pick where you go based on a flow, but when you can have a flow AND live in base....

Don't get me wrong: Endeavor is a good place to be, the DFW-NYC commute shouldn't be too bad, and you should be able to have a line pretty quickly (though getting one that's commutable on both ends will be more difficult), but unless you really need the extra money I'd be inclined to go with Envoy.
