"Rather than" in a specific sentence.

How should this go?
"We are trying to imitate, rather than to delineate juxtapositions. To procrastinate, rather than to extrapolate."
I usually don't add "to" after using "rather than", and so it seemed odd to me. I felt it was necessary to keep "to" as I kept "trying" hidden yet still in effect. So it would sound like, "we are trying to imitate, rather than trying to delineate juxtapositions..."
