Yup, I noticed the same thing. Seems the YN-622C will only relay the HSS signal via it's side PC sync port, which is sorta unfortunate. Was hoping I would be able to rig my existing Pocket Wizards and piggyback them onto the YN's HSS signal, but no luck. I would have to connect the YN-622C via it's PC port to my PocketWizard transmitter, and then attach the PocketWizards to my flashes. Then it'll work, but is a bit cumbersome to do while I'm out in the field shooting. So I'll probably end up buying more of the YN-622C's.
Also noticed that the SuperSync timings didn't make a difference with my RoveLight. It worked equally well at all settings and only made things worse for my Photogenic lights.
I do wish the RoveLight had a handle on it though, for easier maneuvering.
Now, just have to figure out how to replace the umbrella mount...
