"In fact, ALWAYS shoot a spike, unless you're in a club that still lumps spikes in with branched-antlered bucks, which is incorrect but that's a discussion for another time."
I used to follow that same rule myself until I saw a study by Dr. Deer and Charlie Alshiemer that blows the myth about spikes completely out of the water. They studied a herd of bucks, half had spikes as a first set of horns and the other have had forks or better for their first. Not only did both classes grow to impressive sizes but two of the spikes grew the largest racks later in life. I'll try and find the info and put a link here.
