Need your recommendation on what flashes and triggers to get for my Nikon cameras. I want one trigger to control all the flashes. I shot 2 weddings with a guy who owns a Canon 6D and he has a Canon trigger that control all his flashes without receiver on them and that made me think. So I know there is the Nikon SU-800 but that's infra-red which is useless outside so I need a radio trigger. Most important is I want TTL capabilities, I already have 4 radio triggers that I can control flashes in manual but its a pain so I want one trigger to control all flashes. If I need to get certain brand of flashes and trigger I am fine with that.
