I hear a lot about Wood shafts are no good anymore, hard to find good stock etc.. Can some of you experienced guys tell me how to tell the difference. The only thing I can come up with is the rift of the arrow, old shafts I have seen have few rift marks, maybe 1 or 2 per shaft. New shafts have the rift, 1-5 or so and some shafts the rift can go both ways with an oblong rift on the shaft. Is this how shaft markers call some hunter grade, premium grade etc. I have purchased bulk lots of Hildebrandts, Rose City and Surewood. We all know who makes the best shaft, that is not my question. I'm willing to learn, please explain if you would, I would appreciate it.
