I do commercial and editorial work, but not weddings or similar , and use the PocketWizard Control TL system for triggering Einsteins and Elinchroms with a connection for an external Skyport receiver, as wel las and either Canon e_TTL Speedlites or Nikon i-TTL speedlights. I have a couple ofthe AC-9 adapters on order as well. Thye have worked consistently and reliably for me for well over a year now. If I wantto just adjust the output on everything I use the camera's flash biasing controls, or if adjustign the ratio between different lights, I'll use the AC3 Zone Controller module.
If I am working with very long (over 100 feet) camera to flash distances then I pull out my MultiMAX units.
