OM-D - which bag?

I use the Crumpler 4 Million Dollar Home when I want to bring more than just the camera.  It seems to fit a nice combination of stuff with the OM-D.  With the landscape grip attached (but not the battery base), I carry around the 75mm prime, 14mm prime and the panasonic 25mm f/1.4.  Down the sides I have a spare battery, polarizer and 10mm extension tube.

If I'm just out for a walk or doing something active I'll just take the camera and maybe one extra lens (always room for the tiny 14mm!).
