Pretty sure I've never had any aeration problems, and I've never shaken a fermenter (the 60L one doesn't lend itself to picking up and shaking!) - just run off from the kettle into the fermenter from a bit of a height (about a 1m drop) and it builds itself a good fluffy head which I guess indicates aeration?
