Yeah, I top out at my 40L bag, but rarely pack it full. I think the most important part is to make sure you don't have much bag sitting behind your head, like the kind with a closing flap on the top with additional huge pocket in that flap. Once you're pointed downward, the can lift slightly and you're knocking yourself in the back of the head and pushing your head forward.
