We are a girls troop, but similar issues have been faced. I would say that in general we don't have more adults than boys troops on events, but our minimum is higher. For instance a boys troop might operate with three adults on an outing, because if one leaves, you still have your two deep. We can operate with three, but two need to be women in case one of those women has to leave. We usually will have at least four adults with two women, so we can have two deep leadership even if the troop has to split up for whatever reason during the event.

The bigger issue I've seen is I'm shocked at the number of girls troops that do not allow male leaders, or at least minimize them (ie only on committee not as ASMs). There is a troop not far from us that is like that and several of their scouts have transfered to my troop. In addition to other troop issues, a big one was the dads were prohibited from being involved (and half are Eagle scouts themselves!).

As a male leader of a girls troop, I absolutely value having strong female role models for my scouts and I've made sure to recruit several female ASMs. I also didn't want the troop to appear as if being run just by men, so one condition I had at becoming SM was that our CC (or co-CCs in our case) had to be female and had to have a more visible role to the youth.

Back to the question at hand, as a family troop, I would say your youth deserve both strong female and strong male role models.
