I've shot wood for 50 years, but have begun to shoot some carbons in the past few years. Wood has a wide range of spines, so you can buy the spine you need. May need to try a test pack, i.e., several spine steps, to get dialed in, but after that, it's just a matter of buying more of the same spine.
I don't bare shaft. I buy the spine I think is right for my bow, cut them to the length I want, one inch beyond the back of the bow at full draw, fletch up the arrows and shoot. Depending on how the arrows act, I fiddle with point weight, brace height and/or nock point. As a last resort, I might need to move up or down in spine a little.
