Another rookie question. I had a Whisker Biscuit put on my old bow. All of my arrows are fletched at 9:00, 1:00 and 5:00. I see that the biscuit says not to let fletching hit the black bottom portion. I can already see wear in the 5:00 fletch on the 3 arrows I've been shooting. Is it easier to re-fletch the arrows, or remove and replace the nocks? They are older xx75 2315 arrows with the tapered back.
