I got my 580's to sync at 1/400s (with proper SYNC, not Highspeed) with the Flex system from Pocket Wizard, which was frikkin awesome!! The problems was that they were useless in everywhich way when it comes to taking them out of the bag and trying to get them to trigger, plus, the 1/400s HSS was only at 1/1 output. But it worked great and the Odin's doesn't have an option like this at all, and if I go up to 1/400s on them, it's like on camera and every other trigger, you get zero power.
I use to 580's in 60x90 softbox with each it's own CP-E4 pack, and if I go past 1/200s sync, I get no power. I usually use my flashes at near full power, so I don't have anything to work with if I go over to HS.
I dont quite get what you are saying here, the odins will let you fire any flash at up to 1/8000 sec at full power including 580s
