1) Brute force vs. sneaky?
2) Straight laced by the book vs. whatever works? Mixed. I'd rather go with the first choice. But I think that there's a certain solution better than others, and that it's preferred due to being effective and/or easy.
3) Extrovert or introvert? Unless we're really close. Then I'd probably be more of a stalker.
4) Skilled/technical/planning vs instincts/experience? A mixture of both.
