I shoot pretty tough arrow when stump shooting and don't have many arrows breaking on me, even when accidentally shooting into frozen blocks of sand. My nocks, on the other hand, are another matter. If I hit something hard, they frequently break or pop off, regardless of whether I am using tunable nocks or index nocks. I know the solution is to not shoot at things that are hard, but walking up to every target before you shoot at it takes have the fun out of stumping and messes with guessing ranges. I wonder if anyone has any tricks to prevent the nocks from busting. What I would really like is a blunt tip that acts more like a shock absorber, like a simms stablizer, but I'm pretty sure there aren't any on the market.
