Dan,
I save the fiddly bit by making the selection on the 8 bit image, then
saving it. Go back to the 16 bit image and you can load the selection in
perfect register every time.

> The trick you refer to involved neat ways to create better selections
> in 16-bit images (where you can't use things like Quick Mask, Color
> Range or the Magic Wand tool):
>
> 1. Duplicate your image (Image>Duplicate).
>
> 2. Convert the duplicate to 8-bits.
>
> 3. Create you selection in the 8-bit version using Quick Mask or any
> other selection methods.
>
> 4. Move your selection to the 16-bit image. You move the selection as
> follows:
>
> 4a. Using any selection tool (lasso, marquee, magic wand), move the
> tool over a selected portion on the 8-bit image. (You'll know when you
> are over a selected area because a small rectangle will appear next to
> the tool.)
>
> 4b. Click and hold down the mouse button.
>
> 4c. Then, while holding the mouse button down, press the Shift key.
>
> 4d. Holding both the mouse button down and the shift key, drag the
> selection to the 16-bit image. Then release the mouse button BEFORE you
> release the Shift key. Your selection lands in perfect registration!
>
> 4e. You can then use curves or levels or such to adjust contrast,
> color, etc.
