Is it possible to group the following equipment and if so what do I need:

Canon 5D Mark III
Two Canon 600EX-RTs
Two Einsteins (I plan to purchase two Einsteins and if I can figure out how to configure everything.)
Light Meter - ???
Trigger - ???

Will the Cyber Commander make this equipment play well with each other or do I have to purchase Pocket Wizards.

Will the Cyber Commander also act as the light meter so I won't have a need for a Sekonic?

How does a CST Trigger Transmitter fit in with everything.

(I own a Sekonic L-358 and Canon ST-E3-RT)

Thanks for you help.

You can run two parallel remote systems, the Cyber Commander and the EX-RT systems. Keep the ST-E3-RT in the hotshoe, and plug a Cyber Commander (or better yet, a CST) into the PC port of the camera. Use the CC to control power of the Einsteins and the ST-E3-RT to control the speedlites.

The Cyber Commander will act as a meter for the Einsteins, but not for the speedlites (as there is no way to trigger the speedlites in this configuration, and the CC does not have a "wait for flash" feature).

You can add CSRB+ receivers to the speedlites, and the Cyber Commander can meter, fire, and group them (but not power level control). However, I do not know if they would continue to be power level controlled by the ST-E3-RT. If not, you would need to manually adjust the power from the flash head.

PocketWizard TT system can control power of both types, but you are limited to 3 groups, and 6 stops of power range on the Einstein.

So there are options, but there will be compromises.
