not daft at all!

Bounce down to WAV when you've got all your automation and musical content done. Once you bounce down your stuck with what you've got, so you have to have got everything sorted music and ideas wise.

Whilst this makes sense in principle, it takes a while to train your ears enough to know when to correct stuff with the sound design, and when to correct it as a sample. And once you bounce down, your stuck with what you've got unless you go back to an earlier version and rework the part.

I try and make stem mixes these days - once you're 99% sure of what you've got, bounce down all the stems (groups) and mix and master these apart as a new project. Changes your focus and you should be able to get your mix a lot tighter working this way.
