I use Kodak Portra 400 unless there is the subject is highly colorful such as sunrises, sunsets, red rock in the Four Corners Area of the US then I use Kodak Ultra Color 400 or Kodak Vivid Color from my stash in the freezer. The advantage of the Hasselblad or any MF camera that has changeable film backs or LF is that one can change film backs without lossing frames.
