If you increase the weight in the front.....you'll increase FOC but decrease spine?
So why do so many people want a high FOC? Wouldn't that eventually be dangerous?
When going extremely high on foc,you must choose stiffer spine arrows to compensate for the "dynamic" spine of the arrow after adding the weight to the front.
The foc formula.
3divided by30 = .10 x 100= 10%
