be careful of rot sections. the wood can heal from the woodpeckers, but there can be rot that breaks down the wood fibers, I have seen this with windshake which is dark streaks through the wood where a violent wind storm cracked the wood, rot can set in between these splits and the wood seperates, does not heal, and can split along these cracks. if the pecker section is in a highly stressed area such as mid-limb,and has a lot of dark area around them, then I would worry about building a bow from it, unless you are wanting to experiment. I would get it bending early and see how it reacts before spending too much time with it, no fun to spend a lot of time on something that can blow up on you.
