The problem I've had with the lumenocks is that the posts on the side that create the electricl curcuit dig small dents into my carbon arrows. So I shoot very little with my hunting arrows and I'm always concerned about where theposts will make contact with the shaft. I love them but this is a concern for me as well. It also makes a huge difference in how well they fit into the shaft. You may have to sort through your arrows to get a good fit.
