For what it's worth, I'm one of those people with a slightly oddball set of flying experience, and a strong desire not to have multiple logbooks for various types of flying.
My solution is an old "Airtour Commercial Pilots Logbook" (virtually identical to CAP407) and simply make up stickers on my PC which I stick as required to change the column headings.
Surprisingly perhaps, it doesn't bulk out the logbook enormously either, the book is about 2/3 full and still quite happy despite however many pages of stickers on column headings.
CAA, FAA, etc. have all seen my modified logbook at various times and nobody's ever batted an eyelid at the modification.
Alternatively, although I've never bought one myself
these look rather nice.
