don't blame your wood shaft if your nocking point is too low and your nock is too tight. This is what I've learn today. I was bare tuning some wood shaft today and was really surprised by how badly they flew given that it was the appropriate spine. But the nock were definitely too tight, so I enlarged them and the shaft were flying way more better, then rising a tiny bit the nocking point got my shaft flying like dart along the 18 yards between me and the target.
Today is a good day and event after shooting wood shaft for more than 20 years, I still learn something from time to time
