Title: Aluminum Arrow Question
Post by: Todd Greenwald on April 07, 2014, 04:48:00 PM

My daughter shoots a 24 inch 1813 Easton Jazz shaft with 75grain point.  What is a similar spine in aluminum arrow shaft, that is more durable???  She shoots a Great Northern Bushbaby, B50 string, 31# @ 26". She draws 22" and split fingers.  
We have 1/4" & 5/16 wood shafts but she want's to shoot Aluminum. Thanks for your help in advance.

Pick something with a similar rating but in a thicker wall thickness, maybe a 1616.  The last two numbers in the size is the wall thickness in thousands of an inch.  Your 1813 is 18/64 in outside diameter and .013 wall thickness.

I shoot 1716s full length with 100 gr points out of my 33# longbow drawn 28". They may be a bit stiff for her. Worth a try maybe.

If you can find some 1516s or 1616s I would think they would be the more likely choice.

An 1813(7.9 gpi) has a deflection of 0.874. A 1716(9.0 gpi) has a deflection of 0.880. You could get the 1716 to tune easily
