Why it Matters?

Rule 705 permits leading with the opinion before the supporting detail, which is frequently more effective than building through methodology first because the jury knows where the testimony is going. The countervailing consideration is that opposing counsel can then attack the basis on cross before the jury has heard it. Sequencing depends on whether the methodology or the conclusion is the stronger material.
