Sample spreads of each direction

This first direction focuses on the different sizes and weights to show emphasis, then uses different grays give emphasis. Lastly it uses different fonts to give a different feel to each part.

The second direction incorporates the background colors more. It uses the size on the page and the capitalization to give emphasis.

The third direction uses different opacities along with multiples of the same word to express the typography. 

I feel each of these spreads are successful int their own way and I don't know which is more successful. I do know that I can use some of each spread in the final direction I use.
