So there's no quality difference between the three, though, so I could hedge my bets and use SDII without sacrificing anything, on the possibility that I might need the region/time stamp info for something, sometime? (I will have to check to make sure my 2-track editors all support SDII, though... I know Peak does, not sure about Sound Forge...)
