I like to use she for a couple reasons. One she is the correct pronoun. Two when discussing something I can use pronouns more often. For example of team evil and team good we have in the female column: Haley, V and Tsukiko. In the male column we have: Redcloak, X, Durkon, Elan, Roy, and Belkar. Makes my life easier.

P.S. I would also like to point out we don't really need pronouns for V. We can call V "V" when a pronoun like he or she is called for and "V's" when her or his is needed.
