The only buck I've ever mounted was my Wyoming high country buck. I did the full alert pose (can't remember the actual name), and with the head slightly turned to the right, about 20 degrees or so. Initially I really liked the sneak and semi-sneak, but as I was going through some pics I had of the buck on the hill two days before the season opened, he was always on high alert. I even have a video of him and he was moving real slow and cautious, taking a few steps then holding his head up high and scanning all the hillside below him, moving a few more steps and doing the same thing. So because of that I decided to do the high alert pose that I did, since that's how I remembered seeing him as I was watching him.
I don't have a picture of it that I'm able to upload now but I can later.
