Re: Any choices other than AE lock, manual, or not using spot?

In the scenario I was describing, the focus is likely to keep changing since it is a live scene with shots taken every second or two. So you have to keep lifting your finger and re-focusing and re-metering and recomposing.

Also, if you are doing multiple shots of a continuing scene or situation a second or so apart, center-point-and-recompose requires you to keep cycling through the focus and recompose sequence, which is dizzying after a while.

No.

Just tested with a 550d with the Shutter/AE lock buttons set to "AE lock/AF" aka standard back button focus setting.

The exposure is locked by pressing the shutter button half-way and then if you keep the shutter button depressed after taking a picture the AE is still locked. If you fully depress the shutter to take another shot it is at the same exposure, and the exposure stays locked until you fully release the shutter button.

So you'd only need to recompose once - so long as your finger didn't slip off the button or you relax your grip...

It would be much better to have the metering linked to the selected focus point.

Yes, definitely.
