How to Choose the Right Arrow Spine for Your Bow
Selecting the correct arrow spine is crucial for accuracy and bow performance. Whether you’re using a compound or recurve, this guide will help you navigate arrow spine charts for compound bows and make informed decisions for your setup.
Understanding Arrow Spine
Arrow spine measures an arrow’s stiffness – how much it flexes when shot. Proper spine selection ensures:
- Consistent arrow flight
- Optimal energy transfer
- Reduced fishtailing or porpoising
Using an Arrow Spine Chart for Compound Bows
Most manufacturers provide spine charts considering:
- Draw weight (measured at your draw length)
- Arrow length (tip to nock groove)
- Point weight (including insert if applicable)
For example, a 60-pound compound bow shooting 29″ arrows with 100-grain points typically needs a 340 spine. Always consult your specific bow’s manual and arrow manufacturer’s chart.
What Happens If Arrow Spine Is Too Weak?
Underspined arrows (too flexible) will:
- Fishtail in flight
- Group inconsistently
- Risk damage from excessive flex
- Potentially cause dangerous failures
Measuring Spine for Recurve Bows
The process differs slightly:
- Use a recurve-specific spine chart
- Consider your actual peak weight (not just marked limb weight)
- Account for finger release (adds more flex than mechanical release)
Does Arrow Length Affect Spine Selection?
Absolutely. Longer arrows act softer:
- Add 1″ length = subtract ~5 lbs from spine requirement
- Shortening arrows makes them stiffer
This is why arrow spine charts for compound bows always include length columns.
Top Recommendations
For a 60-pound compound bow:
- Easton Carbon One (340 spine) – Best for target shooting
- Gold Tip Hunter XT (340 spine) – Ideal for hunting
- Black Eagle Carnivore (300 spine) – Great for heavy setups
Pro Tips from EliteArcher
- When between spines, choose stiffer for safety
- Temperature affects carbon arrow spine (stiffer in cold)
- Always test arrows before hunting season
