FOC on Trad Arrows -

Can some of you trad guys tell me how important FOC is on a Traditional arrow?

Hey Booner,

In my experience shooting trad bows, FOC was important. The I always felt like the more FOC I had in my arrows the quicker they would stabilize and would do so with smaller/wetter feathers. I also felt like it would aid in penetration on shorter shots as an arrow flying straighter will out penetrate an arrow that is still wobbling in flight, and arrows wobble or paradox pretty good coming out of a longbow.

I also read an analogy one time that went something like this. If you JB Welded a brick to a wooden arrow shaft and dropped it brick end down it would pull the shaft behind it in line with the brick. If you dropped it with the brick at the top of the arrow shaft the brick could easily shift to the left or the right of the shaft and not impart it's full weight to the shaft on impact. This was an extreme example that was designed to show that there is an actual effect on arrows with the FOC is increased.

For me, personally, I believe I get better arrow flight quicker with a higher FOC and I believe good arrow flight is essential to good penetration. Hope this helps.

Foc is more important with trad setups when tuning carbon arrows as they are normally very stiff in spine and also relatively light in weight as well. Heavy inserts and/or broadheads decrease the shaft spine and increase arrow weight, especially tip weight and I believe it does make a difference in penetration as well. I can shoot my arrows with 100gr inserts and 125gr tips without any fletchings out to 30-40yds with no problem and that is when I know I am tuned perfectly. I always bare shaft tune my setups with the desired tip weight I want to shoot and trim down shaft length to adjust and it works plus it gets my arrows up in the 500+gr range that I like as well.

think about it. A yard dart is very short and all the weight up front. how fast do they stabalize and how deep do they sink in the grass? very fast.

FOC is important for all arrows, not just "trad"

I just went out in the yard with a wood shaft(no fletch) with a nock and 125 field point. Throw it like you would a spear. Try it with the point first and watch it. Then try throwing with nock first, sometimes it will turn in flight so point is forward. With no weight on either end the shaft will go in different directions each time it is thrown.
FOC is needed to insure good arrow flight, as with any good thing, if you get too much then it becomes not so good.
