Above is what i have so far for a double page spread.
Changed the leading over all to give the bulk of text a little more clarity, also uses the space more efficiently.
Fractually changed the leading to separate the paragraphs.
I like the TW cen typeface with the bulk of text however i don't think it works with the headers. Ive changed this to Century gothic. To change the subtitles of each screw ive put it in italic which i think works nicely
