what would you do?

So, say you're writing a book chapter, and you have a colleague with whom you sometimes write these chapters with, and you're not writing it in your native language. Say furthermore that your writing style tends toward literary flourishes and parentheses within whole parenthetical paragraphs, not really the clear and direct scientific ideal.
Your colleague is, however, a native speaker and something of a grammarnazi, and for a few chocolates you can count on her to put the text into shape. And to rein in your wilder speculations.
Do you:
A) plan out the chapter with her and keep her informed both of your progress and of the looming deadlines
or
B) don't bother the colleague with boring information, wait until the reminders start coming from the editor before starting, and then the day before it's "really" due, ask your colleague if she might have a few spare minutes to look over a couple of pages?
Hmm?
What would you pick?
