So I'm going from PW plus II's and speedlights to this system, am I overwhelmed?, yes. I've watched some youtubes, but still overwhelmed. A simple 101 on how this system works would be good. I'll be playing around in the meantime. https://www.youtube.com/watch?v=qa1_i3Re63M he goes into depth I'm sure I dont need, if someone has a simple intro vid, I'm all ears. Thanks (not pictured Xpro-C).
