re: TifTuf, Tahoma 31, or Tifway 419 Bermuda in Dallas?

I have Empire zoysia in a section of my yard and St. Augustine grass in the other. In the beginning of drought, zoysia is usually the first to brown up (dormancy). But even a little water and it bounces back quickly and completely. St. Aug. is not as fast to brown, but when it browns, a good chunk of it dies.
I would think hybrid Bermuda would be the best at “drought avoidance”. But it’s also gonna need a reel mower for mowing several times a week and more fertilizer (in general; I don’t know the specifics of each variety you mentioned).
