You know that you are highly unlikely to be able to transfer offices as an IEA. It can be done, but it isn't likely without a hook.
If you stay an IEA, you get to keep your AUO, OT and 6c. You will stay a 9 with the chance of going to 11 at some vague point down the road. You will not go higher without promoting or 1811, both actions would result in you no longer being an IEA. You will also stay in TX.
If you go with FPS, you get the 12 and get to go home.
Is 6c worth that much to you?
