Most of us pre flight smart used them exclusively.
Remembering you independently extracted the data, couldn’t mark the book with the told card and the old told card had the speeds. (Are you still using them?).
This of course was in the day when you had the PDA and printer and a good FO knew the exact position to get the best infrared connection. Yes OM6 used to be a lot bigger. Plus there were two volumes and a full flight library on every flight deck.
Which also meant there was a good opportunity to have copies of the manuals. Even if they were a cycle out of date.
