RE: ladies arrow/head combo?
any arrow cut to proper legnth and proper spine will suffice...id try to get a decint weight..i wouldnt go super light or super heavy..
as for heads...id go with a cut on contact head..something like a magnus stinger 2 blade head for the best penetration from a light bow..
get her shooting good and teach her the killzones and tell her how important it is to make that arrow count and find its mark and she will have no problem bringing down game.
