coach campbell (about your products)

I am looking to put together a power run offense that has three basic formations. The "I", offset "I", and single back (tw tight ends). I was looking through you product offerings and saw you had a manual entitled "The I Back Offense" as well as an I Back Video Series. Does the video series contain the same information as the book/manual, just in a visual format??? Or is the information given in each different??? Exactly what are the differences between the two and how should I decide which one would better suit my needs as big time high school and/or middle school offensive coordinator.

thanks
