Since realizing that you can't use manual mode with the transmitter & speedlites, I'm trying to figure out a decent set-up. I have 18 in wedding party in church, with 3 speedlites available. I think I'll eliminate the transmitter & use one on camera as master & the other two as slaves bouncing off umbrellas. The set-up I am referring to is on page 33 (the top diagram) of the speedlite manual. Speedlites all using ETTL. Camera is 20D, settings, ISO 200, 1/250, f11. If anyone has time to look & comment on this set-up, I'd sure appreciate it!
