Although just my opinion, when lighting for docs, I tend to go with less. No need to try and match a "Dateline" look with 15 instruments. I'd go with KinoFlos Interview kit (one 4 light, 2 - 2 light) I'd probably throw in a few 300w Arri's with dimmers to light anything in the background. Other than that, less is more - go with it!
