The higher your front of center is the more arch your arrow will have, the lower the FOC the flatter shooting the arrow will be, anywhere around 10% should be plenty for stability and good trajectery
This is a myth.It doesn't matter what the foc is.a 500 grain arrow with 10% focwill fly the same as a 500 grain arrow with 20% foc,from a trajectory standpoint.This is puttingspine and tune aside.AND providing all else is the same.The foc is not a deciding factor in trajectory butweight is.
