I've been doing a fair amount of traveling lately too; shooting a lot of interviews for corporate clients. I've kind of forgotten about the Tota as an option, which I've used before. I think I might include one in my kit for my trip next week, they take up almost no extra space. Thanks for the reminder!
I have been going out with whatever Arri fresnels I can fit into a small case, which is usually a 150w, 300w and either a 650w or a 1k ArriLite with a soft box and a reflector.
