For outdoor, daytime stand-ups we usually roll with an 800 HMI, 4x4 or 6x6 with either 1/4 silk or full stop silk, sometimes a reflector or Astra for fill, if needed. And obviously, try to avoid shooting a nuclear background, especially if you're in the shade and don't have natural light helping illuminate the talent. I used to use black nets for the background a lot back in the SD days, but haven't been a fan in HD. As a matter of fact, I think I threw most of mine away, because they dry rotted.
