Print Manual

Been thinking about a few cover designs to get me running with the inside of the book in terms of layout etc. Also some design sheet ideas of how the cover could look - keeping them related to print.
I have narrowed down my choices to a select few typefaces - for headers / titles etc I want to use
Helvetica Neue Condensed black  Legible / Professional / Modernist
For the body of I am undecided but the few I am experimenting with at the moment are -
Orator Std - Only issue is that its only got uppercase letter forms
Lucia Sans Typewriter - Used it before but I know it works, legible but not as standard as Helvetica
