Any one Interested in finding out what it is if they don't already know? They are the easiest way to tighten up your groups in a way you might have not even thought possible!

Ok so basically everytime you shoot your bow, your arrow flexes or "oscilates". As long as your bow is in tune the arrow will flex the same direction everytime. Why? Because the arrow always has a stiffer side that remains constant. Imagine putting the field point of your arrow on the floor while having the arrow straight up and down and pushing down hard with your palm on the nock (dont do this as it would hurt) your arrow will start to bow. As long as the conditions stay constant the arrow will bow in the same direction everytime because there is a stiffer side to the arrow, or to put it differently a stiffer part in the grain of the arrow. So a dozen arrows that you have made up with the void vane fletching glued on already if you were to do this same test the arrows would all bow different directions right? Well thats not good for consistency! So there are a couple of different tools called arrow spine testers that test which way your arrows have a natural tendency to want to bow when they are shot. When using the spine indexer you mark all the arrows on the side they want to bow toward and you glue your void vane on that mark so every time you knock those arrows up they all always have the natural tendency to want to bow the same direction and oscilate the same way therefore increasing consistency. Not more accurate just more consistent shot to shot!

OK this goes back to my days with cedar shafts and using a spine tester and lining up the grain but I suppose it can apply to carbons but at a much lower rate and with far more consistancy than wood arrows have.

Right same process. Its just that like you said carbons are way closer to start with than your cedar shafts. I could see it making a huge impact on the consistency of actual cedar shaft that have a grain.

With the consistancy of carbons I wonder just how much of a difference it would make to the hunting archer to try to spine match carbons? I think out gear out performs our abilities. I like to pour over the tiny details (perhaps more than most) but I wonder if this would really be noticable |

Right, the average hunter may not see a difference. I shoot a fair amount of 3d and some 5 spot, and I can notice the difference at longer ranges. But If it boosts your confidence its a plus, as a big percentage of archery is in your head not your equipment anyway.
