I have the 300 II and I'll echo what others have said...at high shutter speeds you can leave IS off.

Not using IS will give you longer battery life. But with the large battery of the 1DX the power saved may be insignificant.

You may want to consider the 1.4xIII extender. It will provide 420mm and still give excellent IQ.
