Enjoy the 600EXs I bought three about 4 months ago. I packed up my other PocketWizards and never looked back.
I was always having some issue with connections and not firing. I have not missed a flash yet, and I am really excited about the GROUP function
(which is only operational with the 1Dx and the 5DIII, I wrote about this in an earlier post).
I like to set the groups to manual and adjust them individually.
Enjoy.
Sorry no comment on the strip box
But I am using umbrellas and parabolics. Thinking of adding more 600EXs to have mutiple speedlights in each set up.
I dont miss my old set up.

Thanks
