RE: Checking arrow straightness
I put a LOT more effort into spinning them when they are hunting arrows than I do with anything else. My hunting arrows I will cull them for straightness, and this year I also plan to use the G5 arrow squaring device as well for my hunting arrows, for the $40 or so I get spend on that I should be able to salvage more arrows per dozen to pay for the tool fairly quickly. Last season I ended up with 7 acceptable arrows out of a dozen green label GT hunter shafts that were within 4 grains of each other finished, and straight.
For 3D arrows and indoor spots arrows 99% of the time I automatically cut 1" off the back of a new shaft, then the rest off the front and then a real quick spin on my pine ridge spin tester to make sure they aren't way out of wack, then thats it. I think I have only seen one arrow out of the last 4-5 dozen pro series that I have bought that I culled for straightness so I usually only spin them right after they come off the jig then thats it. My FITA/Field arrows are a different story though, I am messing around with some X10's right now that are awesome......their specs are unmatched by anything I have ever seen before.
