For me, neither are an issue. This is because I don't feel like I'd be able to shoot a turkey with a bow with out a ground blind. I have one store bought blind, but I don't really like it, but use it if there is rain in the forcast. I prefer natural cover (dead branches/evergreen to fill holes). Not real sure what broad head would be better, but I can't imagine that it matters much.
Good luck,
KP
