Thus, what we have called "joint methods of delivery" are open to much personal variation. You must decide for yourself which is best for you, for the occasion, for your subject, for your audience--for these four factors all have their individual claims.
Whatever form you choose, do not be so weakly indifferent as to prefer the easy way--choose the _best_ way, whatever it cost you in time and effort. And of this be assured: only the practised speaker can hope to gain _both_ conciseness of argument and conviction in manner, polish of language and power in delivery, finish of style and fire in utterance.
