RE: How to increase FOC
 

I tried it and unfortunately they dont seem to include Carbon Express arrows in their equation. Oh well it looks like i will be buying lots of arrows and broadheads this summer;)

You didn't look hard enough. Carbon Express certainly IS on there. It's the next one down the list from XX78.;)

For someone who doesn't have their brand listed, they can get pretty decent results by using an arrow that is listed and has similar specs.
