Arrow weight and FOC aren’t separate settings — they pull against each other. Here’s how mass and forward balance work together to shape speed, penetration, and forgiveness.

Total arrow weight and FOC decide how deep an arrow drives and how forgiving it flies. Here’s how balance point works, how to calculate it, and how to tune it.
Quick Answer: Arrow spine is the stiffness of your arrow shaft, written as a number like 340 or 500 — the lower the number, the stiffer the arrow. To choose the right spine, match your bow’s actual draw weight and your arrow length (not draw length) against a manufacturer’s spine chart, then adjust for point […]
Quick Answer: The archer’s paradox is the fact that an arrow flies straight to the target even though, at full draw, it points slightly off to the side of the bow. It works because the arrow shaft bends and flexes as the string releases, wrapping around the riser and snapping back onto the intended line […]
Quick Answer: Paper tuning a compound bow means shooting an arrow through a suspended sheet of paper from about 6 to 8 feet away and reading the tear it leaves. A clean round hole means your arrow is flying straight. A tear with tails pointing up, down, left, or right tells you exactly which way […]
Carbon vs aluminum arrows isn’t about which is ‘better’ — it’s about matching shaft material to your bow, budget, and goals. Here’s how to choose with confidence.
Measure arrow length from the nock throat to the shaft end, find your safe cut length at full draw, and cut carbon arrows the right way.
A hands-on walkthrough of building your own arrows in 2026 — from reading a spine chart honestly to cutting, fletching, and verifying the finished shaft on the bench.
Bareshaft tuning is the fastest honest read you can get on a compound bow. Strip the fletching off two identical arrows, shoot them next to a fletched group at 10 yards, and the unfletched shaft tells you exactly which way the bow is fighting your form. Paper tuning catches gross errors. Bareshaft tuning catches the […]
An arrow is the variable your bow can’t fix. This 2026 guide walks through spine, shaft material, fletching, and FOC so the arrows in your hand actually match the bow on your hip.
