I use the Pooleys version since that appears to be the only one where you can write the route into the FROM To box since most my flights start and finish at the same place I would have no idea where I have been. I also have a java totaler for the mind numbing adding of the hours.

I have used a self designed database logbook for since 1986. Unfortunately it was done in DOS. Printing became a problem in XP and program won't even run in Vista. So a couple of years ago I searched for a Windows based logbook that would let me import all of my DOS info, over 20 years worth. Logbook Pro was the best program I could find. It is easy to customize to let the pilot track anything they want such as mountain time or long line time. I recommend it. Keeping military time seperate from civilian time would be a piece of cake.
