This is an older thread but naturally it's my home area so I feel obligated to comment.
Lots if great advice here, I was going to suggest the east side of the Metroplex for maximum of both amenities and access to good bass water. East side puts you closest to lake fork, richland chambers, tawakoni, cedar creek, lavon, lewisville, ray roberts, grapevine, arlington, and ray Hubbard. West side has some older reservoirs and closer access to possum kingdom. Both sides are within a couple hours of Lake Whitney and also Texoma which are absolutely worth fishing. Smallies are probably best in the north half of the state but generally never get much above 7-8lbs max so your options for that are limited. But there's excellent LMB, Crappie, and Gar fishing out this way. And if you go down south you can seek out Guadalupe Bass. As much as the human population size here makes me insane, it is a pretty awesome place to live if you're into black bass and also Costco
