Advice? Learners' sanity & engage Interactions

I have figured out how to 'chunk' the knowledge in my information-based course.  I feel five interactions will do the trick. 

Question: Based on your experience, would learners appreciate the information in different types of Engage interactions, using the same type of interaction to maintain consistency or a mixed-approach (three the same type, 2 different etc.).  I know variety is the spice of life, but consistency is key to good pancakes.

Certainly, some of the Engage interactions work better for my information than others, then again I am trying to use the interactions in a creative way, not merely how they are labeled/demoed (i.e., using the timeline format for something other than a timeline.)

Any advice based on your experiences or learner feedback is welcome.  Thanks!
