I shoot just raw. I shot raw + jpeg for a while but always just ignored the jpegs anyway. Sometimes I feel silly dragging the huge raw files around after a day of snapshots or when the bulk goes into the bin anyway. I am running out of storage. But a good number of my shots require the capabilities of a raw file. Sometimes I expose a shot counting on those raw file capabilities, or often I make a mistake in exposure and it is "raw to the rescue".
