I'd drop him like a hot box of rocks. Wouldn't think twice about it. The areas I hunt I just don't see bucks like that, I think because if road poachers. There are gobs of does walking around, but bucks bigger than a small basket 6 pointer are pretty scarce. That deer has a good sized rack (it'd be the biggest buck I'd ever shot, BTW), and it's not a crusty old deer with stinky showleather for meat either. Best of both worlds.
