I had two and just sold one. I figure that the sb800/600 work just fine in tandem. Plus I've got an sb400 for fun stuff too.
One of the 600's was always on one of my cameras at a wedding. What I mostly noticed was that it didn't recycle as fast as the 800. Otherwise I never noticed much difference. The 800 has a commander mode and is a bit more powerful. But so does the camera so that doesn't make much difference. Both work like troupers.
do you use CLS on your cameras? or use PW/Cybersyncs?
I only need 1 on cam flash for now...but If I want to do strobing, if I use either PW/Cybersyncs then I guess I don't really need the commander mode of the Sb-900 right?

its easier to understand how you explained. it.
