If it's big planes you are after I get that it may seem worth going back to the RHS. I would be very surpised if you dint regret that pretty quickly.
Flying for a bigger better name, well I've been there and done that. If that is what you seek you could go DEC A330 at many in China, Korea, et all. If you go RHS there is never any gaurantee of getting back, airlines are screaming for DECs bothe scarebus and Boeing you would be incredibly foruntate to give up command and not regret it.
Please tell us all what you do purely out of interest!
