Awesome buck! To me, that buck screams to have it's head low. He carries the mass so well, I would consider full sneak with a right turn to show off the deeper fork. At the end of the day, probably can't pick a bad mount on a buck that nice.
I've rattled in a ton of whitetails. However, the largest deer I've rattled at turned and ran from it. Just depends on the individual deer, some are fighters some aren't.
