Whirly, I think I like the sound of your logbook a lot more than some sanatised "offical" model
Mind you, given that these things seem to last for years (my father's isn't half full yet and he used it for at least 7 years before he stopped flying - he's now restarted so there's this page where the first flight is 1982 and the last is 2002
), I'd like to get a really tough one (in bindings and paper) at the start. There doesn't seem to be too many of them to choose from though, so I'll probably use one for reality and one for the IAA with copied data
