My trick apart from the great tips you've shared (used them too), is provide case study, examples that touches the heart.
If you walk the talk of the things you present... the validation is so strong that the answers you gave will 'shut them up' and 'make them gasp'.
hahaha, i love to see the audiences expression all the time when i answer tough questions... it's rewarding ... Loved it!
