When Radio Popper introduced the PX radio triggers I never used my Speedlites in Optical Wireless again. I have owned Phottix Odins and Yongnuo 622c radio triggers as well but all these work around, add on radio triggers create just as many issues as they address when converting the wireless optical system to radio. The 600EX-RTs are not perfect by any means but in a Speedlite only enviroment they are hands down better than any of the previous EX Speedlites.
Canon has left the 600EX-RTs and Wireless RT system wanting for more but, having the RT system built into the flash and the new <Gr> Groups mode is the game changer.
If your going to bash a product in a thread where people are being nostalgic about it, at least get your facts right.
The Radio Popper system took the Canon optical wireless system and translated into a radio signal, then back into an optical signal.
The Phottix Odin and Yongnuo systems work like the Canon RX system do, they take the ETTL signal normally passed directly between the flash to the camera through the hot shoe, and turn it into a radio signal.
As far as the camera and flash are concerned, the flash is still operating on the cameras hot shoe, even if it isn't.
Then they add extra features to it, like groups and different channels.
The Phottix Odin takes a very old, outdated flash like the 550EX and gives it the same functionality and usability for off camera work as the new 600EX-RT.
