Commonly made useful advice for any flights that require a declaration is to use a paper declaration done so that it overrides any electronic declaration--there are just too many possible problems with electronic declarations to not use paper, at least as a back-up.

Doesn't the last declaration override anything else?
Which means that the logger needs to be switched on early, before the paper declaration is signed. -?

Technically its when the electronic declaration is entered vs. when a paper one is signed/dated/timed by the OO. Some (older) flight recorders are brain dead and will rewrite the declaration timestamps or clobber the declarations in existing flight logs if you do the "wrong thing" so in general power them on and don't touch anything after entering your declaration. paper vs. electronic has been covered here before and the recommended steps are covered in the SSA guide. World records are different and require a electronic declaration (and suitable level approval for the flight recorder).
