I just bought a dozen Carbon Express Maxima 350's FOC design.
The rep, who I am friends with was telling me that from the factory, when set up correctly, they yield about 12-13% FOC. According to him, this is about perfect for broadhead flight.

This stuff is just rubbish. Ideal FOC depends on the arrow length, static spine, draw length and draw weight. For one setup, it might be 7%, for another is might be 30%.
If I take an arrow with a spine of 300 and shoot it out of a typical 35 lb draw weight, I might need a tip weight of 300 grains to get proper flight. This might yield an FOC in the 30% range. If I take another arrow that has a spine of 400 and shoot it out of a 75 lb draw weight, I might need a tip weight of only 75 grains to shoot properly. It may give an FOC of only 5-6%. Hopefully, the smart hunter realizes that high FOC are forgiving with broadheads and choose shafts and tip weights accordingly.
