Fl,I also put a little more importance on the foc,but it looks like we try for the same thing.I also agree with Sajackson that Easton pretty well keeps it safe for you if you follow their charts.

It has been my experience that for 3d I will keep carbon above 10% as a minimum and aluminum doesn't seem to need as much.Easton reccomends 7%-8% for them.For hunting I like to be up to around 12% for the various obstacles encountered,not just for penetration benefits.

Fl,I also disagree about how much foc helps in the wind.Here in Ky. in the early spring a person can encounter 30-40 mph winds and I have personally watched arrows fly sideways until they hit the target and be right in the 10 ring.The point weight is the main reason but having the least amount of surface area for the wind to catch is a big plus,another reason to use smaller diameter shafts and short,low profile vanes.
