I'm currently making an aircraft "Cheat Sheet" of all the Boeing and Airbus aircraft engines on all the body's from the 717 to the 777 and A318 to the A380. Eventually when I have time I will add more aircraft. I have been using Wiki and the information on the A.net site as a source, and have run into some slight differences. So I'm wondering what all the engine options are for the 777-200, 777-200ER, 777-300, and 777-300ER. Thanks, once I am done I'll upload it and if anyone feels like it look it over and see if there are any errors.
