More than likely she will not be making a shot at a deer more than 30 yrds out and more like 25 yrds and under. Shot placement is far more important than gaining a little speed at that distance. If she's shooting good with the set-up she is using now I would stick with it. Experiment with other options after the season is over....she'll kill a deer with it the way it is now, just keep her practicing every chance she gets.
