I checked a couple other FOC calculators and they said not to use the length of the broadhead in the overall length part of the equation. If that's the case, the FOC with my setup is 10%. What would happen if I went to 125gr broadheads?
FOC is not your issue. If you went another 25gr on the head it would make your setup weaker, then you would have to drop more poundage off the bow. If anything you need to go to 75gr. Don't get wrapped around the axle with FOC.
