I am convinced, based on my research with the YN-622s and my AB1600, that one can HSS with the Phottix Odin directly wired (not wirelessly!) to the AB1600 or Einstein (not AB800 and lower). With my 6D, AB1600, and YN-622 I was able to sync up to 1/2000 very well when wired from the transceiver to the Bee. Want to ask before buying an Odin. Anyone? Many people could benefit from such a test! Thanks!
