all comes down to personal work flow, forme its, any work or something that might need more fixing always shoot RAW, and for personal stuff, holidays pics etc i shoot JPEG, rarely i feel the need to shoot both, but try both and see what works. there is lots of debate all over the internet over what you should do etc, but IMO its a personal and what works for you. if you shoot RAW for everythng you will find you are eating through memory very quickly.
