Spine Charts
Technical Info:
- This spine chart relates to an arrow length that is at least 1″ longer than draw length.
This is to accommodate finger clearance from the point/broadhead
Example: 28″ draw = 29″ arrow.
- If however, you prefer to use longer arrows, simply choose the required arrow length across the top of the chart.
- If back tapering the shafts, go one spine group stiffer than recommended.
If barrel tapering, stay with recommended spine group.
Tuning Tips:
- If your arrow wags left and right that is a good indication of improper spine- usually weak spine.
- For Right handed shooters: If your arrow flight is good, but arrows are impacting left of point of aim, then the spine is too stiff.
- For Left handed shooters: If your arrow flight is good, but arrows are impacting right of point of aim, then the spine is too stiff.
- For Right handed, Asiatic shooters: If your arrow flight is good, but arrows are impacting right of point of aim, then the spine is too stiff.
