I remember being involved in topic a few months ago (I think it was on this site). It went on for a few days and during that time I searched every place I could find for "facts and studies" on the subject. At the end, there was still no conclusive evidence one way or the other. For every article I read that said to shoot spikes, I read another that said don't. Most were written by biologists and "experts". Some of the studies were short and did not take place under normal living conditions for a whitetail (meaning free roaming, un-managed etc). If the experts can't even agree on what to do, I don't know how the hunters are suppose to decide what to do.
