TO me, its important not to be in a rush to get them done. If you rush, you'll miss something. I straighten before I start, then leave them overnight and straighten again as needed. After staining or dyeing, do it again. I check them between each step. I putthem in my cresting motor to see how they spin, then also eyeball them. I cut them about an 2" longer than the finished length so I don't waste time straightening something I'll be cutting off later. Straight arrows crest much better and evenly.
