What is arrow FOC, what does it do, why is it important, why and how does it affect arrow penetration, and how is it measured? Those are questions I keep getting over and over. FOC seems to be one of the least understood dimensions of arrow design. :confused:
I try to answer every single email and PM I receive as fully as I can, but what, where, when and why FOC questions requires an answer too complex to fully explain in a compact message.
Thanks to everyone, if you'll direct anyone with questions to this article first. That's the Christmas present I'd like most!
