I've never seen anything I like in the way of a pilots bag/case. I am always on the look out for the traditional flight case that's smaller than the std size 19 inch, hard to find they are. They where popular years ago with Airline drivers but I simply don't see them advertised anymore here in Aussie outlets. Anything else these is an adaptation of a computer bag or is a dedicated soft flight bag more aimed at the recreational driver.
Each to their own I guess.
