If I may offer an advice, I would correct your first post to clearly state that you only mean the Rolls-Royce-powered 777-200ER, not the -200LR. I would also include the non-ER -200. It's much lighter and may have comparable fuel burn (not sure). The range is incompatible, though.
Otherwise it'll cause more confusion.
Just a thought.
