Biologically, there’s absolutely no reason not to kill either one, as they both appear to be 5 or older. Any 5 year old is a trophy regardless if he scores 100” or 150”. You should be proud to get the chance to kill a mature deer in AL, whether it be one or both of them. There’s more to a trophy than whether it’s getting mounted or not. Sounds like you have control of the property, so it shouldn’t matter if you want to mount it or throw it in a ditch. Go kill em.
