NotDylan, to answer your question better, yes there is a way to do this. If you are wanting to use carbon shaft then pick the size(spine) that is most likely to work for you. Leave it full length. Put the insert, and point on it that corresponds with the weight broadhead you want to use. The idea is to start out with a shaft that shows weak MOST of the time, and then trim it down from the nock end until it flies straight. This is a very simplistic way of doing it, and there is more to it than this but this will get you in the ballpark. Read up on arrow spine and know what it means. Understand what you are doing each time you make a change. If you want help, do not hesitate to get a hold of me. I can walk you through the way that has worked very well for me.
