I agree memory checks of the truly important safety items such as fuel on correct tank and sufficient, trims set and controls free are the important things to do before every take off..
When landing I use a slightly different memory check just prior to landing.
Turning final I always once more ask my self, where am I landing and where is my gear? I always do that both fixed wing and rotary wing.
P.S.
When in Britain I do this memory check when turning finals.
The reason being that turning finals exposes me to at least twice the risk as turning final.
