Common wisdom says that female/female debate teams don't win.
The reasons are complicated, including sexist notions about how women should communicate and the fact that women don't often stay in debate long enough and focus on it enough to be highly competitive...
but, the bit tournament has a female/female team in the top 8 (at least one, as there are two teams I don't know...).
They are up against seniors who have been uber-competitive for four years ---- so beating them won't be easy.
On the plus side, what I know of the 5-person panel leads me to think that the panel is a pretty good one for their style.
So -- go FM!!!
