Double Page Spread Font

On my front cover and contents pages, I have stuck to using a few key fonts -

Rock It

and Defused

Both of these fonts were found on dafont.com

However, for the double page spread these fonts have proven to be too difficult to read in small size. I have solved this problem by reverting to a standard Ariel font for the body of the text, using Rock It only for larger portions of text.
