Listening to few podcasts with arrow builders and they say you don’t get the real effect of a heavy foc until you get to around 20%
I totally agree it’s not needed I was just wondering why it would take 20% to see real effects or benefits.Whatever "real effect" is. I guess when I start chasing elephants and Cape Buffalo, I'll figure that out. But for NA, 20% certainly isn't needed, and probably not even recommended.

There is a lot of commentary on Uber FOC on these forums. ...and there will be guys that drank the Kool Aid that disagree with me- but here goes.
I too got wrapped up in EFOC many years ago before a Water Buff hunt in Australia...and spent a lot of time trying to get that very high 30% FOC recommended by certain folks.
What I got was an arrow that was less accurate. Of course YMMV....but it destabilized my arrow. Then I applied some common sense and realized we aren't talking a missile or another projectile. The same weight up front that stabilizes an arrow in flight....DE-STABILIZES it on the launch. All that weight up front has a strong effect on your arrow spine on the release making that EFOC arrow a lot more unstable. There is no free lunch in physics.
Then I realized a lot of the claimed benefits of very high 30% FOC was not done in controlled testing- like with a hooter shooter....it was a below avg shooter with a stick bow. And then some of those tests are with wooden dowels and rubber bands.
I concluded the guys pushing 30% FOC never back tested it against the exact same weight arrow with avg FOC like I did....as the avg FOC arrow was consistently more accurate. All that extra weight up front made shooting that setup more critical...especially of minor form errors that happen on something like a hunt.
I think a guy is better off concentrating on developing an arrow that has perfect flight, a tuned bow that shoots his BH's to the same POI as FP's and if he wants more penetration- shoot a heavier arrow. The heavier arrow has the added benefit of making your whole setup quieter.

I’ve found that using a lighter GPI arrow with a good amount of weight up front is best 125 head + collar and brass. You can achieve 15%ish FOC and keep your speed up too.
