My attitude now is that I will shoot raw, especially if I'm likely to be getting something worth keeping (rare, but it happens..!

The only time I will go back to jpeg is if any of the following apply:

- I need to take a huge range of pictures (900 jpeg per 4gig card, versus 200 raw)
- I need to do long continuous burst shooting (my cam does 50+ in jpeg, and about 11 in raw)
- I don't plan on doing any post production and need a very quick output workflow for some reason

Otherwise, it's RAW by default now, even though the workflow, though more painful, gives better control.
