using your method the chart suggests i use a redline 460 spine
using my method the chart suggests i use a redline 520 spine
now i have read on this forum that alot of people suggest the easton chart suuggests all too often a too stiff an arrow, using your method i would agree, but using my method the tuning is spot on.
i know because another archer in my club uses 31" 460 spine redline. even with the extra length they came out way too stiff for my bow, yet the 520 spine the chart suggested using my method are perfect,
This method was taught to me by my coach JOHNSKE on here who has over 40 years experience in archery and was also a supplier of equipment to archers over the same period as well as reaching State coach, so he has seen the differing easton charts over the years and noted the changes and therefore understands how they work.
all i can suggest is to try our method |
Well, you can ignore Easton's instructions if you like....
The notes on the (paper) charts say something like "Actual peak bow weight should be measured at your correct draw length".
It has been contended in the past that Easton's charts tend to suggest shafts which are too stiff. But remember that's better than shafts which are too weak...
But thinking about it, if your arrows are within +- a couple of inches of 28 inches, then the draw weight you measure at 28 inches is likely to be within a few pounds of your actual draw weight, so will probably (unless you are at the edge of a section) fall within the same section of the chart as measuring actual draw weight. Could be up or down a spine, though.
In reality, spine charts are a place to start, not gospel.
