Brian,
Nice looking buck. I'd say 28-29 and low 170's. For me, I'd pass but if I see a buck like that when hunting with my son this year, I'd tell him to kill it. The question for you is, do ya like him? If you do, drop him if ya get the chance. If you have to convince yourself that you like him, then let him walk and hunt hard lookin for something that you do like.
