If your broadheads are shooting fine, dont worry about it...if it bugs you, wait til off season to make changes....too close now to start over. My experience is a 3lb drop will not be the end of the world and cause spine issues....its better to be a bit over spined than under. Right now I am shooting 3 very different arrows , not having made up my mind for elk yet....two of the arrows are very much over spined, and it is NOT an issue for me....might be for others, but Im not experiencing any problems. We all have opinions here, you will have to sort it out and work it out for yourself....WHat works for one, doesnt necessarily mean it works for another.
