Disk space is dirt cheap, so why are "large" raw files an issue?
If it's worth shooting, it is worth raw, except perhaps journal/sports/news type applications.
Shooting jpg is to surrender nearly all the control to the camera. When the camera applies post processing to the just made picture, it does it "big bang", meaning that instead of surgically applying, for example, sharpening, or contrast to specific parts of the picture, it applies the tweek to the entire picture....not good, not good at all.
Often, those that shoot jpg mostly, and complain about how long post processing raws take, are those that don't know PhotoShop, and/or have poor post processing skills...all of which is a very lame excuse to shoot just jpg.
