I am going to use my 47lb Onza for turkey hunting. what would you use for an arrow and Magnus Bullhead combo? I have some full lenght Axis 340s and was thinking about which head to use 100 or the 125 Bullhead. Will fletch with some 3" vanes, either Fusions or AAEs. Other arrow will be my standard with a 100 grn 4 blade Buzzcut.
