Really the pose of the mount is an individual choice. I figure out where on the wall the mount will go and if there is a better side of the rack I want to feature. I've got 5 basic shoulder mounts, head up and one sneak. I like the sneak better than the others.
A good friend carried his son, 10, to a early hunt a couple of weeks ago and the kid shot a 255# hog of a buck. I called a good friend that is a taxidermist and he mounted the buck last week so the kid will have his buck for Christmas. A 4 week turn around.
