I think you have a tremendous opportunity on your property to produce some incredible whitetail with your management concept! I would strongly encourage you to go for it.... the only way to tag the older bucks you want is by passing the younger bucks up..... it's that simple.You can't shoot a 5 1/2 if you putyour tag on a 3 1/2. I don't have the luxury of unhunted neighboring properties but even so I don't shoot 3 1/2 year olds. I want the 4 1/2+ that score 150+. You certainly hunt an area that produce both the age and the scores..... go for it and best of luck to ya!
