Kevin I rarely straighten arrows again after the initial bends. I may whack the side of a tree and have to bend one back. If they are bad enough I cant straighten them they get flu-flu'ed. I cant speak for all, but I have made probably thousands of arrows from many materials and never really noticed any not staying straight nregardless of the material I used. Heck some of my cane and boo shafts wobble like a wet noodle, but they fly like darts. Parallel machined shafts are a different bird. Its hard to line up the nock and tip if there is any wobble at all, they have to be straight through their length. Cane shafts just need to have the majority straightened between nodes and then its all about getting a point end and nock end spinning true to each other. I still suck at shooting, but boy do they fly nice missin'! Sorry for the gust of wind..
