If you drawing a fair map you should draw it using 2016 and then estimate with the boundaries for 2010.
Population change is pretty big.
I know, I couldn't find the 2016 files though. So I basically left the urban seats underpopulated roughly 60k each.
And Republicans are hurt big time by geography I realized, particularly in Harris County. The Republicans are mostly clustered in northwest Harris County and the eastern part of the county. You basically have to gerrymander the county to give them more than two seats.
