Personally if I had a herd/land to manage I'd let the "bad genetics" go until the last day of the season unless I got a nice buck before that. Or maybe I'd take the "big buck" one year and the "bad genetic" buck the next, and just go one that that switching from one to another. Just wondering about the people that take out the undesirable ones and let the nice ones grow bigger. When do they take the big one?
