When I first ventured in to raw, I started shooting RAW + JPEG for a couple of months, I gave that up as a waste, of time and storage, I was wasting time trying to work out if each JPEG was good enough or not, then processing the RAW's into another JPEG, so storing one RAW, large fine JPEG from the camera, then a larger JPEG (less compressed than the camera) from DxO.
It was this situation that had me shoot RAW with all cameras and set large fine JPEG as an option on a button if I want something I can quickly pull on to my phone and email, don't think I've used that yet either.
Or do what I do and shoot RAW+JPEG. RAW to CF, jpeg to SD. When you get home you have both and can use the one appropriate to the end product.
