Here's something else I thought of . . . If cutting down the arrow increases the spine, then how do you know what the spins is after cutting it down. Is there some graph or mathmatical way to determine this?
I'm shooting 27.5" draw and arrows are cut to 28. Axis arrows. I was told that if you shorten the arrow, you stiffen the spine.(?)
Well, even if you do figure it out, mathmatically speaking,what exactly are you going to doabout it? You typically only have severalspines to choose from. If you cut an arrow down .5 inches then more than likey you will still have to use the same spine of arrow. With bows today it is probably better to shoot a stiffer spined arrow.
Besides, arrow chartscombine arrow length and draw weight to determine thedesired arrow spine. If you are between arrow spines I would personally go with the stiffer wall. To each their own ...
