I honestly don't understand your question.
In that video it seems you already have the bounce physics working in some way. Are you using physics materials or are you using coded forces?

The hover/spring force is a must for these times of games, however small of an effect it has, there's no real point in trying to avoid using it. Using physics materials only goes so far, and when you want to make more customizeable physics it won't work as well as having the forces coded from scratch.
I'm stuck with final exams until july, but after that I can help you more directly if you want.
