Don't worry, the [RHA] isn't brilliant at PvP either these days.
About Omega 11, the radiation shouldn't be too big of a problem. If you fight in areas that have less radiation, the damage from it should be minimal (i.e. maybe 5 bots throughout the whole fight). Besides, I think it's a nice additional thrill/danger factor.
As for the day and time, I'm good with Friday, don't know about everyone else though. It's the last work day in the week for most people, so they're usually at home and don't have additional obligations.
I'll try to be there on the [RHA] side. If you need any help in organizing, let me know.
