Teaching has always to do with bringing something really new and perfect to a still quite fresh mind.
So, when teaching, you always need to bring the simple and perfect theory.
Practice is what your students will make out of your 'perfect' theory -- slumming down quite a bit -- but if you start with bringing a 'practical' theory to begin with, your students will never learn to fly high (bringing in some really fresh new ideas).
