It just occured to me Dan, did you check the straightness of your arrow alone? I am in the process of throwing out a few gold tip hunters that are no longer straight. I've shot the spine out of them. If I had to guess I think I've shot them several hundred times each. I checked them all when new and now they have a big fat wobble to them. I hope you have an arrow checker, LOL! I'm sure you know how to make one in ten minutes or so if you don't have one.
