Be Good doesn't create meaningful choices or clear bonus situations.

Lucky in Love doesn't create complications, just mostly advantages.

Alcoholic has very limited helpful applications.

You want something that is going to cause trouble, but you also need to clearly imagine how it could be used positively. Ask yourself, Will I enjoy the problems this causes? Will the other players? How will this help me? Will it come up too often? Often enough? Will it be too much of a problem? Or not enough to matter? Is it unique enough to be interesting?

These questions make the mechanical choices for Role and Maneuvers easier because you get a clearer picture of the character, what kinds of problems they frequently deal with, and how they go about solving them.
