I have found that broadhead tipped arrows with FOC's above 12% perform better for me. I even have a set of Easton FMJ's that have a FOC over 20% and they are awesome.
Raising your FOC to 12% to 15% can improve flight, groups, and penetration. FOC is just one of many variables to consider when building the ultimate hunting arrow.

Easton recommends 10-15% and imo,this is mainly due to spine.Below 10%,you can have serious flight issues,especially with broadheads.
If you choose the HIGH foc route,you need to make sure you are shooting a stiff arrow to accomodate the extra weight up front.
