Nine times out of ten I leave the lens hood in the case. Most of the time I've not seen a difference optically with or without the hood. It does offer a bit of protection to the front of the lens, but then so do lens caps and I threw most of the front caps to my lenses away (really they're in a box in the cabinet).
As a working photojournalist I try to slim down my gear as much as possible when I have to hump it all day long. When running and gunning with a couple of cameras around my neck, I find the lens too long and unwieldy with the hood on. When I really need a lens hood on the 300 and don't have it, it's not too difficult to improvise one with some paper and a rubber band.
Thanks for the feedback. It is funny- looking at the 300 2.8 sitting here without a hood it looks so small...I realize "small" is relative, but I would agree that while leaving the hood at home wouldn't affect weight all that much, it'd be one less thing to pack.
