Another cool post. Being a mere lawyer, I don't have a huge bag of tricks but one that I have learned is when someone finds something I forgot/missed/overlooked I immediately acknowledge their insight and suggest that my oversight might be even worse than they suggested. Here is a made up example: Leaper says, "You forgot the usury provision in the note." Lawyer response, "You're right, usury could be a big issue in New York I think I should focus on this more, do you?" Leaper, "nah, just make sure the provision is in there." The usury clause goes in and the topic is never thought of again.
