EVOLUSION ARROWS SPINE CHARTS
The Evolusion Arrows spine charts are your essential reference guide.
Unlike simpler spine charts published by other brands, ours include more factors that affect arrow spine selection:
- a range of suitable point weights, and
- variations on bow set-ups.
There are two spine charts – Hunting and Target – specifically formulated for the Evolusion Arrows range.

Why does the Evolusion Arrows spine charts show a recommended point weight range with each spine?
To determine the correct arrow spine for your bow-setup, it is vital to include the point weight in your calculations (the combined weight of the point plus insert/outsert).
If your combination of bow draw-weight and arrow length leads to a spine and point-weight combination that doesn’t suit your requirements,
- arrow too light or too heavy
- FOC too low or too high
You may need to vary your set-up to build the perfect arrow:
- use a slightly shorter or longer arrow
- or use a different point weight
- or reduce your bow draw-weight slightly
- or use lighter or heavier vanes.
