That's just a PURE gimmick. FOC isn't going to make that arrow penetrate 2.5" more.

I would be willing to bet that the CE is less than 1% more in the FOC department. I shot them last year, and then switched to Gold Tip Pro Hunters. There wasn't much of a difference. Pure marketing gimmic in my opinion. Not saying they aren't good arrows because they are, the FOC part is bull though. Once again, I liked the arrows, they preformed great but it wasn't because of the weight forward.
