i'm an author, and i have a book signing set for the launching of a new novel on thursday (yay!), so this question has been on my mind for a few days now.... i have an M1000, but it will be too heavy in the hand after a while, and besides it lays a very wet line that will take time to dry. so maybe i'll use an M800 and/or a parker duofold international, one loaded with blue-black and the other with pelikan brown (but who--i mean which book buyer--gets what ink?....)
