That brings up another question that I have, roughly, how heavy should I be as far as total arrow weight? As of now I'm looking at approximately 400 grains. Thats if I go with a 100 grain broadhead. Now with that said, I normally shoot about 360grains finished product out of my Bowtech Allegiance VFT with out any issues. I realize that I'm comparing apples and oranges but it's all that I know at this point. I'm still stuck in the highspeed world, but I would like to keep my speed up as much as possible without compromising penetration. If that makes any sense.
