There's another school of thought - SD for RAW and CF for JPEG. Like 64GB SD and 16GB CF - for the fact that SD is very much cheaper than CF and D800 files are damn big. So if you want to shoot RAW + full JPEG in a cheap manner, 64GB SD and 16GB CF makes sense.
The cost of a 16GB Extreme Pro CF is about the same as a 64GB Extreme Pro SD BTW.
That is the economy school of thought.
The performance school of thought will be using CF card for RAW, and jpegs in SD. Simply because CF cards are so much faster even though they are more expensive.
