Until you feel like you can get no more from a single light (with or without a single reflector) I would not worry about getting a catalog of techniques. This advice from Christopher Broadbent on the large format forum was the best I have ever received. A year into portrait photography on various formats, and I am still working with ideas with one light. I now have several modifiers with grids and what not, and a huge high power strobe instead of a Speedlight, but it is still one light. Still learning. Amazing what you can do with one light.
