Okay, I've read this entire thread twice now. Interesting stuff. My thanks to Scott for all the field research and beta testing he's done. As I mentioned in the Elinchrom thread, I just received my Quadra Li-ion 'S' head and ECO ringflash set-up tonight. Among other things, I was looking for the ultimate in portability in a 400Ws unit, and I think this satisfiies that requirement. I used to lug around a Dynalite Uni400Jr and a 26-lb Dynalite inverter to produce 400Ws in the field, so the Quadra will be a welcome tool. The CL-600 certainly looks interesting, and I'll definitely be following users' experiences with it here once the product begins shipping. As always Scott, excellent photographic examples!
