I have used logbook pro for 2 years now. If I receive dual, I will have the instructor sign a paper logbook and I won't put anything in the remarks of the E-logbook. If I give dual, I will put the name of the student in the remarks section of the E-logbook (nothing in the paper). When I interviewed last month, I brought a fully printed copy of logbook pro, and my paper logbooks to show the signatures of the dual I have received. Except for this interview, I will print out my logbook pro logs once a year to keep it somewhat updated. Of course if you are interviewing, you will want it to be as updated as possible.
