Thanks Pat. Yea I can spine my arrows and have a testor that is quite effective on spineing. I used to make a lot of arrows for professional shooters and myself and know a thing or two about spine. But I keep reading that people sort their cane by spine before they do anything, and was just wondering why. I spent a few years working with Olympic shooters and have a good sense of what spine is and does. I still spine each and every arrow I make for anyone, but was just courious about the spineing before you straighten them to use a spine tester. I know, I know,,,,taking this too far,,,,but thats the competive side of my arrow work taking over.
