DFW, just don't go there during a push. LBB don't get in SWA's way, they taxi at rotation speed. You'll pass over Abilene with two long runways, and Dyess AFB, that's about all.
You'll probably go to LBB on the worth departure which goes to LBB, never need an enroute chart; and return on the Motza arrival, once again not needing an enroute chart. mostly flat in between with a major interstate highway underneath you most of the way. No dangerous terrain to speak of, lots of nothing.
DFW is smack dab in the middle of the Dallas-Ft. Worth metroplex. You'll find just about anything you want there, including traffic jams leading to DFW at just about any time of the day. Lubbock is a college town, home to the best looking women in Texas. It's big enough to have anything you need, but it's sort of ugly if you like any kind of natural scenery. Friendly people and a couple of good restuarants.
