Thank you Shaz,

I am kind of "old fashioned" for the log books. I used to work with an electronic one for my pilot logbook and got a big problem with it. I had to revert to a paper logbook and write 3 years / 2500 hours of duty manually...
Since then I've reverted to the good old trusted paper logbook for the job and the hobby as well.
As always: keep it simple and easy.
