I'm looking for a simple solution to combining my 600EX-RT's with my studio lights indoors. I know the peanut slave is labeled as not compatible with the 580EX on B&H's website but, I don't know what the issue is or if it applies to the 600 as well. I like the idea of just plugging a slave into the PC jack and still being able to use the nice Crane coldshoes that I have for my lightstands. I guess the other option is a hotshoe type slave but, the Wein has terrible reviews for horrible quality control.
I guess there is also the option of firing the Speedotron packs with an optical slave and controlling the 600's with the ST-E3. Just trying to be simple, dependable and economical.
BTW, right now I fire the Speedo packs with Skyports.
